Well, it's good to have an option to upgrade to DDR3 WITHOUT upgrading the motherboard. That's why I got P35C-D3SR.

whats ur oc, fsb and heat now???

I posted earlier:

If I'm not wrong, you can never measure the Northbridge temperature...if so the Southbridge is at 42-43°C at room temperature.

where u post dude? just tell me le. need to compare if mine running too hot or ts okay for now?

Huh? I just quoted it for you just now.

oppsss. sorry. blur edi.
thanks mate.

CPU = E6550 @ 3.5GHz (FSB 500MHz), Rev G0, BIOS F9
Mobo = Gigabyte P35C-DS3R, Rev. 1.1 (A2)
RAM = 2GB Corsair Dominator CM2X1024-6400C4D (500MHz, 4-4-4-12)
Heatsink = Thermalright Ultima-90i (Zalman 92mm & Silverstone 120mm)
vCore = 1.34400v (vDroop 0.04350, BIOS set 1.38750)
vDIMM = 2.2v
CPU Temp = 33°C (Idle), 53°C (Load) - ORTHOS test
Mobo = 42°C (Idle), 45°(Load) - ORTHOS test - not sure if temperature reading is actually South or Northbridge.

hai guys,need a suggestion,my fren wanna buy intel C2D e8400..is this proc easy to overclock??

How about asking him/her to wait for the Core 2 Quad (Penryn)?

lambat lor bro,..and the price i think should be high punya..

Hmm...increased the latency of my RAM, and see what I got Let the pictures do the talking.

IDLE
[attachmentid=388266]



LOAD
[attachmentid=388268]

Added on January 27, 2008, 5:39 pmOh, btw, my heatsink is Thermalright Ultima 90i with Zalman 92mm (26xx RPM) and Silverstone 120mm (18xx RPM). Forgot the model number, dy.

Dunno where to ask so I ask here lor....

Can my PSU support Q6600?

@izwan
dont u think u should go research that, rather than ask a noob question like that. Yes it does support

Lol I know I'm a noob....juz wanna know is it enough with my whole rig power consumption...and the Q6600 will be OCed....

I'll answer for you, 'kesian' la

Yes, it can support quads in your system. no worries.

something goes wrong wit ma rig, check da FSB:DRAM 4:5, but others 1:1

You have to set the ratio yourself at the BIOS. Running 2 instances of SuperPI will not stress your computer enough. Use Orthos or 2 instances of Prime95.

Added on January 28, 2008, 5:35 pmThe Gurus here, may I ask what are the difference for the ORTHOS priority settings? I can't seem to pass the highest with the new FSB 515MHz...sigh.

Thanx bro!!U're my fren!!

why i cannot go higher already?? 2.9 cannot logging windows already...

Set the FSB:DRAM to 1:1 first lah.

FSB 515MHz failed Orthos Priority 10 but passed OCCT High Priority.
[attachmentid=389781]
Googled and found that Orthos may have issues with Vista...oh well. I guess if OCCT passed, then it should be ok.

issit my mobo version problem?? make my proc cannot go up again..

You can try playing some of your favourite high resources intensive games to see if it's stable
I'm using Vista with Orthos and no issues. Btw, you can still run compability mode in Vista.

Orthos Priority 1-9 no problem after 2 hours (I'm too lazy to do more than that). Orthos Priority 10 fails in less than a minute. Weird eh? OCCT High Priority no problem as well. I tried Bioshock and GoW (others are not as new and I haven't touch Crysis yet) with no problem after several hours of gaming. I didn't count. 3dmark06 is doing fine, MemTest as well, SuperPI is a no-brainer, along with my other resource intensive programs, 3dsmax, Photoshop, Illustrator and Revit (all handling Gigabyte files without crashing). So, what's with that Orthos Priority 10?

Did you try to set the FSB:DRAM to 1:1? Increased voltage for vDIMM, vCORE and others like FSB, MCH, PCI-E?

I think you've done enough test and as long as you can enjoy your games, etc without hangs then it should be fine

Alright...taking it from the pro Will try to achieve 3.7GHz if possible...but I doubt it'll be ok.

LOL, thanks but I'm not really good at this thing yet too. Maybe we can explore it together
Btw, what HSF are you using now?

thats a really good proc u have.
low vcore.

Which one? My E8400 needs 1.408V (actual voltage) to be stable at 4.1Ghz - running more Orthos to burn in now.

sorry meant kevin wcw...

so high vcore for u to reach 4.. 500x8 or 445x9.

dude seriously i have been playing around with this proc for a few days..
its always been sometimes not enough or too much nb/pll and fsb termination..


TIP:
1.Set a vcore voltage depending on ure cooling. ( u should know roughly how much it can take at load)

2.Load into windows are a reasonable voltage and mhz speed that i know definately will work.. etc 9x400
with relax mem timings mem usually 2.2-2.3v

3.Use memset and set at spd timings or epp profile if u have and overclock with setfsb

4.a)Run orthos small fft priority 10.. if pass 10 minutes keep increasing to the next 5mhz
b)if fail like close to 10 minutes.. will lower it to priority 8 then must pass 30 minutes..
then try occt 30 minutes..if OCCT fail.. must be NB/PLL voltage increase..
try again with different NB and PLL.. if pass then continue on

i usually do a increment of 5mhz and then once if it fails i do a decrement of 2.5mhz

5.Once i find the best setting then will go for long time run Orthos priority 8 blend 2 hours priority

6.Set in Bios and do a OCCt 30 minutes to double check on the blend and run memtest windows.. try to empty all ure mem amount till u left less than 50mb left.. run for around 20 minutes.. or 1000%. with no errors..
use memset to change ure main timings.

heck u can game anything with this.
oh yeah here is a kicker.. for another test on NB/PLL..
if ure download torrent using utorrent.. while running ORTHOs etc set the utorrent to cache mem around 64mb.
if ure mouse gets laggy any time u move around the screen.. means mem/nb/pll/fsb termination unstable

There's no choice to it If it needs 1.4V stable it means 1.4V - can't discount or whatsoever.

I'm talking about a stable overclock but if I want to do Super PI like what you did, I don't need 1.4V.

Anyway, I'm still experimenting so it's too early to tell.

thats my definition of stable above.. and for me that can game.

everybody definition of stable is different.
so even say 12 hours priority 9.
memtest boot 24/7...

what i was trying to point out for u was the e8400 has 6mb cache and requires more v's on the NB and PLL
than C2d 6850 which we barely take note off especially the G0's since all the p35/x38 was made for them from scratch bios/ voltages etc.

try it and then u might believe me.
i am not saying a big drop in voltage but a bit..

this is y i changed my stance on the e8400 4.5ghz being stable..

all i can tell u is i am finding it hard to get the nb/pll stable with the rams..

whats the point if u pass 6 hours of orthos priority 8 if ure mouse is laggy when utorrent is downloading at 100kb's??

also now testing multi..
it seems i need more vcore on multi 8 compared to multi 9... this wasnt the case for the e6850/e6600/q6600 that i tested with this board..
but it depends on the NB/PLL.1000mhz sandra score at 9400-9500 is no joke

as far as i know in XS they state that the X38 chipset will be unstable at 60C above.

also i found out sometimes i force it to pass orthos with vcore.. but it will fail memtest even on lax timings with multiple errors.. ..

been spending the past few days night till afternoon testing this.
like my proc has a fsb hole at 447/480../503/

hi guys..
just bought p35-ds3 rev 2.1
i try to OC with this new mobo..
there are three mode in the bios : standard,turbo,extreme
which one should i use?I have tried the standard option,the multiplier is 9 and when i raised the fsb,it shows the speed are not equivalent than what it should be.
For example 400X9 should be 3.6ghz.But it shows only 3.2ghz.

Hm..

Please refer to the links on how to OC. People in this thread normally do manual OC, meaning we select all the values. Your selection of "Standard", "Turbo" or "Extreme" is automatic OC. Not really good or reliable...to me at least.

I inted to do manual Oc but i dont find the manual options.
So i tought the standard options is the manual options.
maybe need to explore more in the bios.

care to share where is the manual options?

Press CTRL+F1 once you get into the BIOS. Even without that, you still can adjust a lot of things. Read the links please.

ok thanks bro.
will ask again if got any problem.

Actually the Gigabyte board manages to OC the Core Duo best. I tried with Foxconn Mars and Abit IP35-PRO but both of them doesn't do as good as the Gigabyte. No ideas why

Hmmm, Abit not doing that good? Saw many reputable sites giving it double thumbs up...along with that Foxconn Mars. How about ASUS or DFI?

I got NBTD so I thought I just whip up a basic guide for noobs on overclocking the E6750 or Q6600..... should apply to any other C2D/C2Q

Look here : http://forum.lowyat.net/index.php?act=ST&f...0#entry15451675

Link in my sig too....

Note : Still in progress but the basic OC is already in place....

p35 dr3r better for oc?

or p35 ds4?

some1 selling in garage sell.
intent to get 1

hmm edited.. gigabyte thread..

the p35dq6 was not bad in clocking only ram was an issue.. like 800cl3 was a problem..
the 680 bus can clock well.. but overvolted and burned some rams..

@kmarc

nice nice.. kmarc soon to be legend for e6750

solved!

The post you entered in was too short. You must have at least 10 character(s) in your post before it will get posted.

DS3P is enough,from ds3p to dq6,basically are using same pcb


i think newer bios remove this already

No la, just a simple guide for noobs only..... Last time I did one for AMD CPUs too.... dunno where it went ady.....

please help/teach me

i have NULL experience in OCing.

What are the steps to OC a proc? I know about voltage, ram timings, FSB. But i don't know what to do. If i have a 2160, what do i need to do to oc it without voltage increase? what's with Ram timings in this? 4-4-4-12? what's that for? 5-5-5-10? huh? OC means change FSB only? how? how to OC?

no wonder i tried many times but still cannot access there.
then what should i do?

See my simple new guide - link in my sig....

excuse me, how do i change the FSB:DRAM in the bios?
