ah_khoo, thanks and I'm running on 2.00 so in a way, yours should be faster if you're doing it at 2.5 Maybe I should try that as well.

Btw, how about the other optimization settings like "Extreme", etc. Do you set everything to the max?

i always put everything to manual / normal, inherit d habit from dfi as manual still d best way to get d best outta every component bro.

ah_khoo, thanks and I'll try it out further tonight and post some screenshots/benchmarks. I'm still new to all these so lots of guidance from the pros like you are very much appreciated

Btw, I also share the same LCD as you do, lol.

bro, i'm not a pro, when u guys were playin with k7, i was still a pc noob...

pr0di9y and u are few of d veterans that i can remember...

Apologize for that ah_khoo but I really do think you guys are more knowledgable than me. I didn't know you still remember this old man

Btw, what is your Vdimm, FSB, NB voltages for your overclock?

ram @ ~900MHz, vdimm = 2.0v
fsb and nb voltage increased by a notch bro, btw, kucing did mentioned that can leave these voltage to stock if fsb is less than 450.

It depends on case by case. Even if you hit the FSB wall at 400fsb...increase the Vnb might just help you push the wall further.

Thanks ah_khoo
450 * 8 = 3.6Ghz - Nice overclock bro!

ya it depends, but assuming the CPU has hit the 400fsb wall, increasing Vnb wouldnt help either, especially on those E2XXX.

nolah, not my case, i'm doin 8*36x only currently. i've did a quick check, think d fsb wall is around 395, 400 & above sometimes can boot, sometimes cant...


d guru has spoken...

yup, if d wall is hit even raisin d Vnb won't help.

How do we fix the "wall" or there aren't any fix to it?

there is no definite answer to it. As for me, when i hit the FSB wall at 400fsb, increasing the Vnb gives me extra head room to around 480fsb. Cascading my proc allows me up to 540fsb. So it really depends on ur hardware and cooling.

kucingfight: im using a thermalright ultra-90 + Panaflo fan.

right now testing with:
350x8 = 2.8Ghz
ram@700Mhz (2.00)

cpu voltage is
idle : 1.34XX , 1.312 in cpuz
load : 1.280 in cpuz

other voltages up a notch.. want to see if i still face the cold boot issue. later gonna lower one by one.. gonna take some time to test since the cold boot problem was random b4 this.

btw, ive got a 2" fan blowing onto the MCH heatsink.

temps ~30@idle, max 53@load using coretemp 0.9.4

hopefully i dont get any more bios resets at cold boot *crosses fingers*

for my case, uppin vmch (vnb i supposed) by a nothc is a must when there's oc done, else, i will have this cold boot issue.

any way to set the multiplier not 1:1 or higher?
coz i think my ram is limiting my oc...
now running 457x7 => 3.2 Ghz with stock voltage
means that my ram is doing 914 like that...

depends on the type of proc and mobo you have. For example, 650i or 680i mobo can set lower multi for rams.

if u think ya ram is limitin ya oc, last resort is runnin ya ram w lower multi, not all boards have these features thou.

u can try to use low fsb with high ram multi, see how far d ram can go, correct me if i'm wrong...

So E2XXX is hopeless for overclocking? Or have to choose stepping? M0 steeping good or not?

E21x0 is hopeless in oc? u gotta be kiddin me mate. don't expect a chip to be able to do 100% of oc easily, not with air cooling atleast. am contented to run my e2140 @ 2.8~2.9GHz, on stock it only runs @ 1.6GHz...

I'm running ORTHOS at 8 x 400 @ 1.375Vcore but CPU-z and Core Temp is not reporting the Vcore correctly. Is this a normal behaviour?

Btw, my full load temp is at 69C now. I think it's time to replace that stock cooler

It normal....what you set in bios is sometimes different in windows. It's caused by vdroop.

tried the f6 bios for p35 d/s3l.. actual voltages are reported in bios instead of OK, and the profiles can be saved... i couldnt save profiles on f4. also, the option1 and 2 for memory have been removed. cant think of any thing else thats different.

i changed to f3 bios since the f6 didnt solve my cold boot problems.. once i know whats causing it maybe ill try the f6 again.

I have the same darn cold boot problem. Btw, what Vcore do you guys run at on 3.0-3.2Ghz range?

Depend on batch, goldfries' E2140 did 3.2ghz with stock vcore.

My E2160 stock vcore max out at 2.9ghz, 3.0ghz at 1.35vcore. 3.2ghz at 1.45vcore.

For P35-S3L, its normal that cpu-z show lower vcore than Vbios u set.
CoreTEMP should only show ur stock vcore, which I believed to 1.325v

Thanks allenultra - how about your full load temps and what cooler do you use?

2.9ghz, 1.325vbios, full load 51c
3.0ghz, 1.35vbios, full load 54c
3.2ghz, 1.45vcore, full load 65c

Coolermaster GeminII with 2 Icute LED Fans

any result for 6550?

I set my Vcore as 1.387 but in CPU-Z, it varies between 1.328 - 1.344
I'm now running at 395 x 8 with full load temps around 66-68C (stress testing with Orthos)

One good thing about this Intel chip is that if you're idling or doing something simple that doesn't stresses the CPU that much, the temp drops a lot (as low as 36C)

I hope I could hit 3.2Ghz soon

hope someone post their 6550 stock vcore result..huhu

Its normal. That's what we called vdroop.
P965, P35 chipset have this kind of "nice" feature. lol
My vbios is 1.35v, speedfan show 1.3v

Hmm, interesting.
Well, I guess I made it to 3.2Ghz @ 1.40675v
The temperature is a sad thing to mention tho'. I either get a good HSF or a water block.

correction there....not all P35 got vdroop. GA-P35-DQ6 has got no droop problem. Btw, what set in bios and what's shown in windows is not called vdroop.

or a phase-cooler ?

If Mr. extremeocer allows credit card 12-month easy payment or 50% off Christmas sales, why not?

LOL.. well he just might who knows ? anyway it costs as much as a real water-cooler unit, and you get lower temps

Yeah, I think it's a good choice to spend on the custom phase change as opposed to a water cooling set I'm more concerned about the reliability of the phase change instead.

I know you guys have the Intel core CPUs, but I have


I have a crap Intel mobo, D945GNT.
together with a overclocker CPU Pentium D 805 (2.66GHz) using stock cooler.

We all know that Intel boards do not have overclocking tweaks in BIOS.

Have checked Intel Desktop Control Center. It didnt list it support this board.

But I googled and found out that people still manage to overclock by using software.

Anyone here got experience on this?

Just wish to OC it to 166FSB(667) FSB or 3.32GHz cpu without cracking my wallet to buy new mobo or cooler.

anyone pairing up gigabyte 965p-ds3 rev 3.3 with q6600 g0 stepping, i got( 8800 gt graphic card,crucial ballistix rams, silverstone 560w psu with it)? any probs with temperature or oc capability? . i dont knwo anything though.. this is the mobo that i bought 2months ago (used).. but still waiting my processor from strongbaby. is it a good mobo for quadcore? i have had read the reviews on it but all based on duo core. just want to make sure its good for quad use as well.. any one can help me?

You have one good system. Rich guy

It isn't the best for quad but it's decnt enough as long as you don't plan to OC your quad. Moderate OC is fine though. You should at least get a P35.

I don't know.. I think technically speaking, the only real difference between a water cooler and a phase cooler is that one uses water and the other uses refrigerant so reliability-wise it's probably the same.

it's decent enuf for dual core but for quad it mite not brin d best outta ya chip. our board (yes, i'm usin d same board as u) has only 3 phase something (power or wat so ever ), but those high end board have 6 phase. however, am please with d board itself considerin d price it cost me.

pls correct me if i'm wrong.

something to share with u guys...

[attachmentid=333337]

[attachmentid=333338]

Hey guys, can some of you share what's the maximum FSB, voltage and timing you manage to achieve with your Hynix FP-Y5? I have been running it at 395x8 @ 2.40 (5:6) which means literally, it's running at 474. The timings are 15-5-5-5 and I have to bump hell lot of Vdimm to it

how much juice u fetch to ya ram bro? i would say 2.2v & below are safe for 24/7 usage. they advice active coolin to be used for vdimm 2.2v & above IIRC.

for d capability of ram achievin certain MHz depend on batch, however, i reckon that hynix chippies can do ~1000MHz (DDR500) @ loose timin w/o any problem...

bro i not rich guy or trying to show off my system la some of the stuff i have is used, upgrade to better rig so that it can last for at least 3years or so. i just want to ask whether the mobo is good enuff for newer generation processor only. whether its good for oc or not. and i list out my other hardwares is to make sure that i dont get flamed/ simple answers such as "you need to have a good psu and ram to accomodate it"

anyway thanks for the feedback guys.. really appreciate it. i am a newbie and wanna try oc so i just try my luck asking here anyway this thread is so helpful.

ah_khoo, unfortunately I need 2.3V to get it running at that point. If I were to bump it higher, it might need even more I'll try it out tonight.

No worries heng84 I was just kidding on the earlier part.

Yeah, as extremeocer mentioned, do get a P35 based mobo, they are optimised for quadcore Ocing (if Ocing is your concern) . else, P965 will do juz fine, but limiting your Ocing headroom



yeah i remember pumping to 2.4v , managed to hit >DDR2 1100 5-6-6-15, on FP Y5, got a screenie somewhere.

hmmm say if i target from 2.66ghz can hit 3.2ghz or not?.. cos have to wait for sometime only then can change mobo.. now really tight budget.

Hi bro.,I'm a newbie here.,i just want to ask.,can I change the multiplier for E6300 in BIOS..tq

I guess my FP-Y5 are total crap? The moment I reduce 0.1V and it turns unstable I need 2.3V to run 474 irregardless. Maybe I should try out Rev A?
