i cant oc it kaw kaw coz of my ram.
anyway.. here is my latest update and this is as far as i can go.

[attachmentid=221376]

yup..but why b4 this i can OC without any problem...been using it at 2.86ghz until 1 day it keeps turn back to stock speed...my fren is using Kingston KVR

what mobo is that?when running 3.6ghz,what is ur idle and load temp?and what's ur vcore?

Guys, my setup is E6300 + 965G-DS4 (F6 Bios) + 2 X 1gb Corsair value select DDR2 667... im having a problem...

when i hit fsb 320 and above wif vcore 1.375, vdimm +0.2, fsb + 0.1 and mch + 0.2, my computer seems to cant detect my hard disk....

Anyone know why is tis happening and how to solve it?

I tried fsb 318 and 319 at all stock voltages and it can detect my HD...

try updating ur BIOS 1st. then procede with ur OC

Yes i already did tat, F6 is the latest for my mobo 956G-DS4

Set the PCIE frequency to 105MHz.

Thx, i'll giv it a try

just to drop to ask something...........i'm plannig to buy a DS3 for my setup...... how do i identify it's rev3.3 compare to others........

the 1333fsb sticker ? or anything else.........

how about ds3 mathcing with value rams ? like kingston pc5400 1 gbx2..... any issue with it........

i have no experince in DDR 2 and C2D setup and overclocking...... DDR and A64 is totally different story

btw i notice ds3 only have 3 phase power, would be be sufficient to run quadcore........ like q6600 and OC it abit till around 3.0ghz ?? should i get ds4 for it then......

DS3 rev 3.3 and rev 1.0 is different from the first look,the northbridge heat sink is different,rev 3.3 got the word "gigabyte" while the rev 1.0 does not have.

and u look at the PCB,every top right corner (try to look at 4 corners),it will written down is rev 1.0,or 2.0 or 3.3,every corner u see,sure got one corner written down,SURE GOT.

oh nice thx ace............... gracious......must go have a look after work......

Still cant, i tried 105 mhz for the pci-e as u said, my com cant even on.... it just keeps on on..off, then on..off..., then on...offf.

Then i tried 100 mhz and 101, oso same...cannot on. When i change back to Auto, it can boot normally wif 333X7 speed but cannot detect my hard disk

Is there any way to solve tis hard disk detection problem? or any other pci-e frequency i can try?

Wait wait wait...

Can't bootup?
Or
Can't detect HD?

You said your mobo could not detect your HD - setting the PCIE at 105MHz should resolve it.

System keeps on & off - this is the typical cold boot issue.
The system should boot normal after power off or pressing the reset button.
Are you using version 3.3? Try bios 11a.
Bios 11a doesn't solve cold boot issue. None of the Gigabyte bios solves cold boot issue as of todate - With bios 11a, you still can have decent overclock after few resets.

Hmm, when i set 320 or 333 wif pci-e to AUTO it can on and i hav the speed i want, but cannot detect HD

When i change the pci-e to 100,101 or 105 it cannot on and keeps on (on and off) as i said

This is the Latest Bios i could find from gigabyte website (F6) which im using now
http://www.gigabyte.com.tw/Support/Motherb...?ProductID=2393
Mine is version 2.0

Try to set at default clock (266MHz) & set the PCIE clock at 105MHz.
Can the mobo detect the HD? 105MHz is the safe range.

The on & off issue is the cold boot.

Hi,

I recently bought C2D 4300 and mainboard Gigabyte GA-945P-S3 Rev. 1.0 to set up my own C2D rig. I'm a budget system builder and have a little idea of overclocking the CPU, not to the extreme but at least, hitting 2.7 GHz,( I know E4300 can give more than that). With the rest of the components as stated in my signature, I set up to overclock. The mobo is Rev. 1.0 that comes with F2 bios. I downloaded BIOS F4 as it is the latest and the flashed the mobo.

As usual, this is what I do to the BIOS prior to overclocking:
- Disable CPUID Max to 3
- Disable No-Execute Memory Protection
- Disable C1E
- Disable TM2
- Disable EIST
- Disable Smart Fan Control Method

The CPU is installed with the stock Intel HSF, and the memory is Kingston KVR667, at 2GB (2 x 1 GB DDR2 667).

As an indication, this is a review of the overclocking potential of this mobo, which is competitive with the ever popular 956P-DS3.

Hardcoreware Review on 956P-DS3 and 945P-S3

After enabling hidden options in the BIOS, I enabled CPU Host Frequency at 201, mem multiplier at 3, PCIE freq. at 100 MHz, no overvoltage and memory still at Auto). This stage is just for testing purposes only, and what did I get? After saving BIOS, the system is like halting for a little longer than a typical restart, and then it booted up without the litlle overclocking than I did. I entered BIOS and I saw that BIOS automatically disabled CPU Host Frequency. After a while, I found out that by
setting PCIE Frequency back to Auto, than this problem is solved. I tested this scenario with 210, 215 FSB and this scenario stays the same. I call this the first anomaly!! I wonder how many of you experience the same.

After fixing PCIE Frequency to Auto, I went on to overclock the CPU further. I put 230 FSB, and the system passed without problems. Then I select 233 FSB (which means 233 x 9 = 2097 MHz), and the system also passed this setting. Easy Tune 5 reported the CPU temp at 47C and +12V reading at 11.92V. So, I said hmmm...pretty good so far.....

However unfortunately that is the last setting that the mobo allowed me to go. Hitting 234 and 235 FSB and so on only resulted in BIOS disabling the CPU Host Frequency, falling back to default CPU setting. Bear in mind that:

- typical E4300 and even E6300 overclockers only start upping core voltage after exceeding 2.7 GHz at least.
- which means, rarely overclockers will start upping FSB voltage before it nearing 280 or 300 FSB (depend on CPU multiplier)
- I don't have to increase DIMM voltage as at 233 FSB x 2.66 mult resulted in 620 MHz which is way below my DDR2 667 rating.
- CPU temperature still doesn't exceed 50 C.
- at 233 FSB, the +12V rail is still reporting 11.92V, no matter what program that I used (Everest included)

Therefore, I'm stuck at 233 FSB where I dont have to overvoltage the CPU, FSB, DIMM, PCIE and not even tweaking the memory timings. My question is: am I hitting what they call ' FSB Wall', or am I having insufficient power, or my mobo just had its manufacturing defect encountered???

I know many will question my PSU, CM Extreme Power 380W being the culprit here, furthermore I also have 7800GT installed in the system. Well, let me give a hint : under my previous AMD64 3000+, Abit KN8 NF4, 1GB DDR400 (and the rest of the components stays the same), I manage to overclock to the Venice core to 250x9=2250 MHz, which indicates how much power I can squeeze from the same PSU. Now, I am hoping that under 65 nm process, 65W Allendale-CPU powerhouse, I can free more power requirement for my rig, which hopefully translates to better overclocking.

However, I need some inputs and ideas from you guys to help solve this problem. The approach is like this: first I am hoping for those who has the same problem as indicated as the first anomaly above to share their experience, and then maybe I need to reconsider if it is true that I need to change the PSU. My thought is that I don't want to buy a new PSU but still having the same problem due to FSB Wall or whatever.

Please, experts needed.

I cannot overclock E6300 with Gigabyte 965P-S3 F8 BIOS. Below is all my system spec.

# CPU - Intel Core 2 Duo E6300
# Motherboard - Gigabyte 965P-S3
# Memory - 1GB Corsair ValueSelect PC667 DDR2
# Monitor - LG L194WT LCD
# Display card - Gecube Radeon X1950 Pro 256MB
# HDD - Hitachi 160GB 8M 7200RPM
# DVD-RW - LiteOn 18X DVD writer
# Casing - Cooler Master Elite 330
# PSU - Cooler Master eXtreme Power 550W

System cannot boot after overclock FSB 280 onward but I can reach FSB 333 in windows with EasyTune 5 utility. I locked memory multiplier at 2 == 667mhz so I do not overclock my memory. But still failed even increase CPU voltage to 1.375 and 1.400.
Any idea? Thanks.

well,not all the processor can do the same.
some of the conroe able to boot @ 3.2GHz at stock speed,but some of them need 1.5vcore to get it boot 3.2GHz,so if u think it cant,then just add some voltage and it might be help u to get it higher.

Added on April 26, 2007, 12:00 pmwell,ur psu is kinda limit ur cpu potential....try to get urself a better psu since u have a 7800GT.
well,Venice can oc with stock voltage la....i oc my venice to 2.7ghz stock voltage.....

when u use the easytune....did you do testing to ensure that the overclock is stable??

be aware that the ram, mobo, psu, power voltage and proc plays a part in overclocking...

make sure that there is enuf power for the proc...increase bit by bit and do testing using the cpu stress test....

to overclock ur proc...u may need better ram....im not sure how c2d works....as i use to play with amd only...

so be careful on wat u do alright?

well,dont use the software to oc,use bios to oc

I was using the Gigabyte 965P-DS3, but i can't Adjust the Ram timing in the Bios, so may i know how can i adjust the Timing, got any tools can make it???

yep...the software is useless... u cant go far with that software.... manually overclock la by bios.

oc at bios..maybe voltage instability...clear cmos and start all over..

Thanks,
Yeah..i know that not all same CPU can overclock the same..but come on man, just 33 MHz more in FSB and suddenly E4300 wont OC anymore? that's kinda lame to me..we are not even talking about 2.3 GHz here...wow

Well, if I get enough votes from you all to change my PSU, I might wanna grab Enermax FMA II 460W due to budget constraint. anyway, like I said, this is the last resort. I don't want to face same problem even after using 1kW PSU later on.

One thing I notice, not many people buy the same mobo as mine.

Sry ALeUNe, had beed busy lately... will try it out asap and tell u the results

ctrl+f1 in bios menu

try and research more about ur mobo....there might be modified bios available out there...where more advanced settings available...maybe...im not saying there is...but if got...then you might be able to oc without problems...try n not lock your ram....and btw.... your sata hdd slot on ur mobo, ensure it is locked...cause if unlock then the hdd also will increase when you oc then your hdd kong....so be careful....and research more alright....

Got a new rig recently,

P4 C3D E 6600, 2GB Corsair XMS2 6400C4 Twin, Gigabyte 965P DS3 rev 2.0 F10 bios, Leadtek 8800 GTS 320mb, Powerlogic Atrix 500W, 250GB sata2 Seagate.

Well, what I got after few tries on ocing this,
1) 3.0Ghz(1.31V), 333fsb, 4:5 divider, ram freq 417.5 (2V) (4-4-4-12).
Temp (core = 41c idle, 56c full load)
2) 3.51Ghz(1.40V), 390fsb, 1:1 divider, ram freq 390 (2.1V) (4-4-4-12)
Temp (core = 47c idle, 62c full load)
3) 3.00Ghz fsb (1.35V). 333fsb, 1:1 divider, ram freq 333 (2V) (3-3-3-8)
Temp (core = 44c idle, 59-60c full load)

I just wanna know, which is the best divider, ram timing and speed in term of performance for the 3 above and because I don't know the answer I chose to settle down at the lower temp for safety reason and for it's longer life span. Please tell me what is the best operating temperature and the maximum limit temp that is safe to use.

try update your bios to f11b , latest beta version, quite good i am using it, my e6400 with ds3 running at 3200mhz , temp is below 50c

Ok just tried tat, 105 at default clock and everything boots like normal

guys, vcore for E6320 1 use 1.4V to 1.5V is it ok, custom wc and temp around 50oC

Damn im still stucked at 318 FSB... eventhough i just flash to the latest bios (F7C)

Everytime i tried 333 wif pci-e to auto it can on but cannot detect my HD

When i put 333 wif 105mhz for pci-e, the cold boot starts happening...

I cannot go stable above current speed.

vdimm +0.3
vFSB +0.3
vMCH +0.3
vcore 1.478v

where i can improve.....

vcore not enough i guess...try put more on the vcore...maybe 1.5V?

Hi sifus!

I currently already have the gigabyte 965p-ds3 but no proc yet.
Its the v3.3

Is the E6600 ES version compatible with this mobo?
Any disadvantages using this ES proc?

it has no problem when installing a ES into it,dont worry,happy oc it!

glad to hear that......

its already been shipped n im eagerly awaiting its arrival.......

I was just wondering. I tried to oc my pc which is running on an E6320 and DS3 v3.3, and sometimes it justs start crashing. Now it's running at 2.24Ghz. I'm actually trying to get it to run at 2.8 . BTW I didn't touch the vcore so it's at its default. Must I alter that? Or someone please show me the correct steps to get it to run at 2.8Ghz. I'm using CM Real Power 450W btw.

WTA.. anybody use DQ6 v3.3 with kentsfield?.. any oc result?? planning on these two babies but wanna see results first..

i know for c2d with some luck we can reach 500fsb++ but how about with kentsfield??

go to serch from the oc database from others [H]forum....

Cfu's here...
Im using Gigabyte DS3..and want to O'Cs my proc...E6600 and Kingston 667Mhz..i got the picture about adjusting the FSB n Memory Frequency..but i dont have a clue for adjusting the Vdimm n Vcore...

The question is...can i adjust the FSB at Ration 1:1 with System Voltage Control set to AUTO....? bcoz every time i increase the FSB the Voltage will adjust automatically..is it safe..?

seems like most other forums only manage to get 400-410fsb for kentsfield

however i saw one forumer in VR-zone forum manage to get 450x8 for their kentsfield ES with EVGA 680SLi..

Why is everyone not helping at all???

Im still stucked at 318 fsb, everytime i tried 320 - 350 i can get the speed i want showing on the bios when it boots but it cannot detect my hardisks..

I tried different pci-e frequency such as 99,100,101 and 105 but all of it are worst than AUTO as it leads to cold boot

HELP HELP

i'm using DS3 and highest achieved is 3.6Ghz...

and then... 500+ FSB not too sure... but that's nothing got to do with kentsfield right? if you push up to 500Mhz FSB...then you can reduce the multiplier to 6 and then you'll get 3Ghz... or at worst 3.5Ghz at x8 multiplier...

4GB is definitely not achievable as of now...not sure if use liquid cooling can or not...

Recently bought E4300 to replace PD820. OC the C2D to 2.4Ghz with all stock settings. All other C2D features are enabled except "No Memory Excute Protect".

hi everyone, anyone here oc pentium d 2.66 b4?..mind to share ur oc result?...below is my pc spec..if i wish to oc to 3.0ghz..izzit possible?..the power suppy enough? coz i gonna 2 sata hardisk, 2 uv tiub , one aerogate II and one dvdrw, and also few fans

Pentium D 805 2.68ghz code name SmithField with Gigabyte G-Power

Gigabyte 81945PL-G with Intel i945G/GZ chipset with Thermaright HR-05

Corsair xms2 ddr2 675 512x2mb

ATI X1300 Pro 256MB with Zalman Fatal1ty FC-ZV9

Tagan TG420-U02 i-Xeye 420W

yup,i used and oc'ed before i sold to forumer.

*this fire dragon is hot enough!i used stock intel hsf to oc to 3.2 (forgot the setting already),i just remember it idle at 60c

the psu should be enough o support ur rig,.

idle at 25'C and then 63'C at max load? seems like not right bro... the delta between idle and full load will not be that much...

I enable the EIST function. CPU multipler stay at 6 when mimimum load and shot up to to 9 when heavy load.
[attachmentid=230092][attachmentid=230093]
[attachmentid=230097][attachmentid=230098]

hehe..ya..this babe is hot..but now i change the stock hsf to gigabyte g power..ideal around +-40...
now i am using clockgen to clock it to 2.8Ghz..without changing anything..just the cpu speed...izzit okie?..or do i need to adjust the pci also?
