i know that 2.2 is safe...for crucial stock 1.8 right??so +0.4 is safe play???nvr play with gigabyte mobo before this..

You do a +0.4 but it's not 2.2V (the voltage drops a bit). If you have courage, go ahead and +0.6V (like what I did). Maybe you can touch the RAM to see if it's hot as I'm not sure how the condition is like in your casing, etc.

oic..so gigabyte have voltage drop...TQ bro for ur information!!!

My pleasure and I believe many boards have that too (unfortunately).

1.6V.... I'm not that daring. Especially when I don't have a backup CPU. Hmmm.... maybe one day I'll try going up to 1.5v....



A few forums did say that crucial ballistix rams doesn't like high vdimm as they can suddenly kaput just like that. Their recommendation is not to exceed 2.2v irregardless of cooling..... Of course, these are personal experiences and I don't know whether you can apply it to all crucial rams....

I've never tried on Ballistix yet (no chance as +0.3V already gives me 438Mhz stable) but previously I had Crucial BH-5's and have been hitting it with maximum Vdimm - never had problems. I did +0.5V on my Hynix earlier too.

I hope I can find a chip that allows me 500FSB 1:1 so with that, I will have the chance to +0.6V on the Ballistix

you're invited to get into Mars planet

errr myaim is not for mars la... i want to EVGA or Asus high end:)

err.. guys..im hving problem here..
i use c2d E6550 n p35-ds3
the highers i reach is 495fsb..my target > 500fsb
im stuck on it no matter how high i increase the vcore..
need advice here..

Did you try increasing the PCI-E or MCH voltage? If you haven't, give it a shot.

That's already good. It's either your mobo or your CPU FSB wall.

My rig can only reach 480mhz..... dunno whether it is due to the mobo or CPU....

err..mch voltage +1v only
but didnt try up the pcie volt yet..
and do i need to set manually the pcie freq?i use ati 3850..

You can set to 100Mhz like what I did and there's no harm to it
Try upping that PCI-E to see if it helps.

waa master clawhammer
thank you thank you..finally reach 500fsb..but not stable~huhu
i`ll try to get more stable result after changing my stock cooler

me and my noob pc..hahha e2140 batch oct, l2 steping, ac freezer pro 7, corsair vs ram, biostar tp35d2-a7...oc to 3.08 max...orthos hang when reach temp 75 though mobo set 85..y?using air zeon 460w, and palit 7900gs oced to 620/775..not enuf power?idle temp at 54

You're welcome sir and no worries, I'm on the learning curve as well
Congrats and try to fine tune those voltage. Eventually you'll get it stable (it's normal to waste plenty of time on this part, lol).

Maybe it's too hot or you need more Vcore to get it stable.

too hot ar?..erm..perhaps...going to lap my freezer...vcore low?i added 0.025 ad le

0.025 is really too little. I need around 1.38Vcore to stabilize @ 3.2Ghz

hehe..after change my stock cooler i`ll continue the journey..
since my vcore only 1.29v at 500fsb..
dunwant to proceed cuz of temprature
i post result later..gtg

hmm adding Vcore does add to the heat.. I think u might need to use MX-2 to aid your cooling. The AC Freezer has a prob with high clocks, made me change it to a cooler with more fins and bigger surface area. It does help to also know your TDP for your proc, as there might be variances in steppings, and steppings do have varied thermal design power.

I'm using Gigabyte P965-DS3 F12. The "other" timings available are such:

ACT to ACT Delay(tRRD) 3
Rank Write to Read Delay 3
Write to Precharge Delay 5
Refresh to ACT Delay 35
Read to Precharge Delay 3

Many has said that they are best to be ignored and left at auto. And my values are certainly different than values of these timings on other brand's motherboard. If they do play a part in overclocking what value's are they best to be at if i were to increase my FSB to 400MHz?


After i overclock my system the BIOS beep sound at startup is different. It's dragging for 2-3 seconds maybe and no longer the simple beep. Does that indicate and error?

You can change the settings, no harm doing that but the tighter you go, the harder it is. If you want to hit 400FSB easier, just change your RAM timings to a more relaxed one, maybe 5-5-5-15?

My CAS, tRCD, tRP, tRAS is okay just that the following is bothering me.

ACT to ACT Delay(tRRD) 3
Rank Write to Read Delay 3
Write to Precharge Delay 5
Refresh to ACT Delay 35
Read to Precharge Delay 3


If i get a different beep sound on startup that indicates an error right? However i tested with memtest86+ and no error was reported. Why is that so?

Yes, beep sound indicates error and sometimes it's because your RAM can't boot up with the settings you applied.

I tried CAS 3, tRCD 3, tRP 3 on my P965-DS3 and Tracer PC2-5300 2.1v @ FSB 400, FSB:DRAM 1:1 . All has error beep, 2 failed memtest+ and only tRP passed. But since there's an error beep, probably not suitable to run at 4-4-3-10 right?


By default on startup there is a normal beep right?

How do i clear CMOS on my P965-DS3 without shorting the clear CMOS jumper? Can it be done via BIOS?

Nope.,you must short the CMOS jumper

wut problem r u facing? u cant start the pc due to the oc?
if u r facing that, then press and hold the insert button when u on ur pc
it will enable u to start the pc...

after that, u can just load the default setting inside bios...

To reset to default setting i should load fail-safe defaults right?

hi guys...
im using e4400 and p35-ds3...
im planning to overclock again, is there any workaround that disable double booting (power on awhile then off, then on again) after i overclock?

Nope. It is a feature of this mobo. However, it only does that when you change a certain bios setting so don't worry about it....

My P965 has double booting too, but then it happens when my BIOS setting is not correct eg. timing abit too tight. After it on back the MIT settings will restore to default. Is it normal?

Any P965 user experience dual BIOS beep sound on startup after overclocking?

Problem, whenever the first boot it will happen but when u restart it ok.

After 2 hours+ of Orthos i encountered an error. My OC isn't very high nor is my timing tight. Could it be that i am unlucky that time, and if i were to run the test it would pass without errors after that period? Is there such a thing?

You can try increasing the Vcore.

Anyone here updated to the latest P35-DS3 BIOS?

I update to F11 latest bios but seem not much different, P35 DS3

Right now got no problem with this bios but my hand feels so itchy wanna update it...but no difference is it?

To me its no different, but you can try to change to the new bios n share with us if there is any differences.

nope...
load optimized default...

edit:

load optimized default: Selecting this field loads the factory defaults for BIOS and Chipset Features which the system automatically
detects.

load fail-safe default: Fail-Safe defaults contain the most appropriate values of the system parameters that allow minimum
system performance.

Ok I have updated my mobo's BIOS and it seems that Gigabyte have corrected the problem with *normal* voltage settings for your ram...it's not auto adjusting anymore and stays at the specified voltage for your rams...However, what confuses me with this F11 BIOS, it seems I'm getting lower scores in benchmarks...any idea sifus?

fulamak

If u have an error at 2hrs orthos i suggest u increase vcore or decreae fsb. An unstable oc once will almost always be an unstable oc later. Maybe u'll have to run it 8hrs to get a failure next time, but eventually it'll still happen

If i finished Super PI Mod with 32M, does it mean my oc is stable? Can i rely on super pi alone?

Does anyone here uses DS3R (RAID version)?
I wonder if it overclocks just as good as the other brothers I'm actually thinking of setting up RAID.

no
because i dont think super pi stresses your cpu to 99% hehe. FOr your system to be considered stable you can use OCCT or Orthos to test for stability.

Thanks alot.


Yup i know, currently lowered the FSB for the time being.

Anyway guys i found out the reason there is an error beep prior to startup. I enabled CPU fan fail detect. Fans on my GPU, and my cpu fan only starts up after the full screen logo. Therefore there's an error beep before the fan turns up.

Yesterday when i shut down my PC and on it back to access the BIOS, it powered down right after i turned it on(no screen appeared), and then it booted. Then the whole BIOS setting of MIT returned to default. Why is that so? I was running my E6320 @ 2.1Ghz stable Orthos for 9 hours.

So my next issue is, if i were to set the same exact setting(FSB, voltage, timing, etc) do i need to run Orthos/Prime to check stability? Or will it be stable since it was stable before this at same setting.

Use OCCT,5 hours+ is quite stable liao.Crazy can run 24 hours.

even 1 hour test is enough man.. it stresses the hell out of the cpu
