The Maximus Formula Thread - Help/OCing/Guide/Rampage conversion

[Zucker2k]

I was wondering if that voltage sounds about right for my q6600 g0. The temps are awfully high, but I don't know if I'll be stable yet.

I don't have to tell you this, but feel free to set according to your cpu's requirements.

hmmm I think I have my ram issues greatly improved now , passed memtest at 1081 where it wouldnt pass at 450 before , but its still unstable , I just want to bench at 4ghz (or 4.1 lol)

Could you post your settings here for your current overclock?

1.52 seems pretty high for a E8400 @ 3.8GHz isn't it? My E3110 could do 4GHz with 1.3. Does the X38 chipset require more voltage clock-for-clock compared to say the P35 or P965?

Leeghoofd is right; the settings above are for a quad, which even at 1.52v (CPU-Z), hardly tops 65C when priming small ffts.

Check out what my E8400 needs for 4Ghz in the screenshot,

Hoep ya clocking with only 2 dimms then Aussie... way easier to get there... but I know you are a tough bloke and like it the hard way

hahaha yeah its two sticks for now , I will get settings up shortly .

I tried more vcore up to 1.65 and it didnt make any different (bsod as soon as load hits). I tried spectrums disabled, I tried setting both GTL manually to max , didnt help. I enabled transaction booster at 3 and got no boot , put it back to auto and booted again.

I tried manually setting multi low and fsb to 500 and got zillions of memtest errors in test 7 , so I set everything to stock and bumped mem speed only to 1066 and it passed. There is also a mem setting for 1200 but with ** on it so I tried all stock with 1200 mem speed and it only got 5 errors in two passes in test 4 , thats with no tweaking and everything on auto so Im sure I could get that stable if need be , but cpu isnt stable anyway .

Any help would be great.

I highly recommend you do the rampage mod to 0401. That is where I found the most stability.

[aussie-revhead]

I will try those , thanks mate , but last time I tried pcie at anything above 100 I get a POST hang at VGA BIOS stage , looks like my vid card doesnt like it . I benched at 9x443 but it was not stable at all , just enough to bench .

You can use the same settings for 9x450, though you may need to adjust voltages accordingly. Goodluck.

Is there a safe easy way to do this ?

[ChaosAD]

Many of you seem to run Q6600 at 1.50+v in bios and NBV at 1.6+. I need cpuv 1.5 which is 1.48v in everest and nbv 1.55 which is 1.58v to run my Q6600 @ 9x425. Although i run games, internet etc stable, prime is not stable at all and sadly i seem to need more than 1.5v real for cpuv. What i would like to ask is how safe is it to run a quad at 1.50+ real and nb at 1.60+ real for 24/7 use.

[aicjofs]

Where do you read the batch # (sticker or PCB, or iC's), cause I got 2 good sets too, and just wanna note for the record. Do you know what chip IC #s yours has? I do know mine are the early double sided 16 ic black PCB. I will state that the stock aluminum cooling is poor for what they need. I replaced w/ ThermalRight HR-07 quickly, since the aluminum models were barely making contact with half the ic's. Again, as I stated way back, this was a big issue, but easily solved. I too can hit 1300MHz but 1266 is more steady for heat and vdimm. Just cool to know they can. I never needed more then 2.28v w/ trd 60 to 1266MHz. 2.22v @ 1153MHz trd 50.

Well batch is somewhat misleading since on the stickers there is a batch number, but most people here talk about a batch using:

http://www.crucial.com/support/identify_parts.aspx

Look at the bottom picture, last digits after period...in the example it's 16fd3. 16 is 16 chips(double sided), 8 for single sided.

I have no idea what IC these are, probably D9GMH, but since I thought they stopped making it awhile ago, maybe not. To be honest I can never keep the memory sorted for the micron D9's...GMH, GKX, HNL, etc, etc. I think you can measure the size of the chip to tell the IC... I'm sure the answer is here somewhere.

General consensus is 10% above vid .

For 24/7 I usually subscribe to the theory of disminishing returns. If you need around .1 to .075 more volts to eek out 100 more Mhz it's just not worth more volts and more heat on a 24/7 machine.

That said, your water cooling looks to be adequate, I would say around 1.55 to 1.57 24/7 if you have reasonable temperatures. But that's only my opinion...in fact personally I stay at 1.5V on 24/7(benching is an ENTIRELY different story though hehe )

I see people running the chipset at 1.65v all the time, from the Intel data sheet that's way over the "absolute max" voltage.(I have read that 1.9V is around the absolute max people have pumped through it with elaborate cooling) I'd top out at 1.65v for it for 24/7, question is...is it really that the north bridge needs that much voltage for 9x425 or do you need a tweak somewhere else. High voltage on the north bridge has a larger role in multiplier, memory stabilty with more modules, higher speeds or tighter timings. I don't think you need more northbridge V then what you have judging by your sig unless you are pulling in some really tight timings on the RAM(Trd or something), I think your instabilty might be elsewhere.

I guess my coolong is ok. Priming at 9x425 @ 1.48v real, CoreTemp report max 53C while it idles around 33C for the hottest core. So maybe maxing cpuv at 1.5v real is ok for 24/7.

Af far as the NBv i ll try to post my full bios setting because what u see in my sig is the setup for 3.6Ghz not for 3.825 that i refer to.

These are the settings i m trying for the moment. Cpu idle @ 33C / load @ 53C. NB idle @ 38C / load @ 43C. Whatever recommendations are welcomed

[aicjofs]

2 ways to approach this.

1. Slow the RAM down, so you can figure out CPU and NB voltage for just 9x425. Then you'll have CPU volts, once you add RAM back to full speed you can figure what extra voltage might be need for NB.

or

2.) I'd give Zen's settings(linked below) a try from "DRAM timing control" on down. Change everything to his except maybe leave your NB voltage and DRAM voltage alone. Then put your CPU voltage wherever it needs to be and test stability. Then work backwards lowering voltages until stabilty is lost.

I tried manually setting multi low and fsb to 500 and got zillions of memtest errors in test 7 , so I set everything to stock and bumped mem speed only to 1066 and it passed. There is also a mem setting for 1200 but with ** on it so I tried all stock with 1200 mem speed and it only got 5 errors in two passes in test 4 , thats with no tweaking and everything on auto so Im sure I could get that stable if need be , but cpu isnt stable anyway .

Any help would be great.

Relax that RAM and back off the performance features for now untill you know your CPU mobo combo can do 500x7. It more then likely will, but too many peepz jump right into cranking the RAM to the gills w/ little room to breath. This is number one reason for many BSOD on high FSB attemps. If anything, use RAM settings to furtther relax to keep it out of the math for now. For 500FSB I need Static Read Control Enabled, but I'd try both. Also try to up the PCE to around 110~115 and SB voltages up a tad to help keep stable Usually 1.10v & 1.6v respectively.

I would set this

Common Performance Level [6] 7 if your ram cant handle 6
If your running 1:1 you will find 4-4-4-12 will produce better bandwidth

should I run 1:1 at 4-4-4-12 800mhz or go to 5-5-5-15 1066mhz at 16:12

[MurderCityDevil]

i was just wondering if you guys know what an instant bsod at load is indicative of. I tried to run 445x9 for 4.0ghz and no matter what voltages i try it gives an instant bsod as soon as I run prime. Any thoughts?

[Grnfinger]

should I run 1:1 at 4-4-4-12 800mhz or go to 5-5-5-15 1066mhz at 16:12

Test both and see, I would suspect that at 1:1 with tight timing it will perform about on par with 1066 so it will be more of a preference.

when ever i bump up to 400 FSB w/9x, I cant seem to find stable voltage for cpu & N/B even if I start in auto and work back froim there, There must be something I'm missing, just not sure where to look. I if anyone has a 3.6Ghz setup on air please let me know your settings so I have a better a starting point

I will really appreciate it

my guess would be the 266 strap is what is causing instabilities. use the 333 or just put it on auto and choose the desired ram frequency for 400fsb.
