sorry guys how to upload image?

BTW....... Happy Xmas.

Been using my GTX295 for awhile now (read: bit over 1 year) at max OC on water with just over stock vcore. I was getting the feeling I wanted to upgrade, but I didn't feel like I'd really worked the card enough and I certainly don't need to upgrade until I see what DX11 brings to various titles. Looking at the results from the guys with GTX 580's I thought that given enough clocks, the GTX295 should be able to keep up.

Volt modded it to 1.19v load, cooling still EK FC295 with cores now 42*C idle, reaching 51*C in ~26*C ambient under max load.

Final stable clocks:

Core= 774 MHz
Shader= 1692 MHz
Mem= 1242 MHz (2484 MHz effective)


Benches with CPU @ 3996 MHz | 1.112 vcore | 3575 MHz uncore |1682 MHz 7-7-7-21 :

3D Mark 03




3D Mark 05




3D Mark 06




No Vantage as 3D mark 11 corrupted it and I cbf fixing it yet. Stupid futuremark not testing before release. You get the idea though. This card is still fast when pushed!



If you have a GTX580 and want to run some comparison runs go ahead it would be interesting to see.

[CryptiK]

Did some BCLK testing today. Got some interesting results and PB's on this board. All results were boot from BIOS.

230 BCLK




235 BCLK




240 BCLK




So I thought I'd test how stable that was with my favourite 2D test, SPI32M. Results as follows:


SPI32M @ 230 BCLK




SPI32M @ 235 BCLK




SPI32M @ 240 BCLK

Nice results cryptik

What was your IOH and ICH volts?

Before i purchased this board i had the choice between this and the ud5, everyone was saying take the ud5, but for some reason, i have always wanted to own a rampage and it was a good choice


Im trying to flashback from the 19 bios to the 1504 bios, I cant find the right version of afudos the support the pbnc/n command

[CryptiK]

Thanks. IOH was 1.35v BIOS set and ICH was at default voltage. The UD5 is a good board from what I've seen. I have kept a copy of 1504 on one BIOS chip so I can flash it over the other BIOS chip (I use BIOS2 for testing new ones and keep a low numbered BIOS on BIOS1 to avoid that ridiculous 'can't downgrade' issue).

LOLS, i did just this

It took me a while, couple of google searches etc figured it out, Its all about the engineering version of afudos

went from the 1913 to the 1504 and now my oc has increased with lower volts, Will post some screenies

Cheers for a such a great thread.

EDIT: I also discovered the 1504 reports temps alot higher than the 1913 bios at the same Voltage and cpu speed, im getting about a 20 degree difference, Anyone notice this?

[CryptiK]

My temps report the same, and from my testing voltage requirements are also the same between BIOSes.

Because of what I do with the 2 BIOS chips re: BIOS versions, I have not needed AFUDOS as yet. Whatever you're most comfortable with is fine, both techniques get the job done.

Fair enough, maybe its cause im on phase, its a different story with voltages and temps, think the evapo head needs a reseat.

I would of used the backup chip but i didnt have the 1504 on there, now i do, as i backed it up after flashing it.

I cant believe the difference in stability compared to the 1913, i need 1.525 qpi to run ram at 2000mhz now all i need is 1.475. I found lower timings are always better when compared to 2000mhz at 1.5qpi.

Just finding a balance between electicity use and performance :P, last electricity bill came to 500 plus dollars for just 3 people in a unit, lols, all my fault cause i need a air con to cool the room down when im gaming cause of the heat from the cascade and pc.

Anyone know if ther eis a proggy other than cpu tweaker which would allow me to change sub timings and cpu multiplier within windows? Turbo v is good, but its limited

CryptiK please post your bios setting,great bclk

[Sanousie]

This is with 2x5850 running stock, Increased clocks to 900core 1150mem only gained 400 points at 1024res



This is my highest oc so far, im sure it can go more, this is prime stable by the way, i can boot into windows higher around 4.7-4.8 but its not stable.

Ugh, electricity prices in NSW are crazy. They increased it what 20-30% under the guise of 'upgrading infrastructure' then the government re-appropriated the money and spent it on other things, then said they would raise prices again to cover the infrastructure. Appalling. Perhaps you should move to water, you can still have great temps (on your VGA's too) with much less noise and less power consumption.

CryptiK please post your bios setting,great bclk

Surprisingly straight forward. Main settings as follows:

Vcore: 1.1875 BIOS
LLC: Off
Vtt: 1.40000 BIOS
VPLL: standard (1.80v)
vIOH: 1.35 - 1.40v BIOS
vICH: standard (1.11v)
vPCIE (IOH & ICH): Both standard (1.50v)

PCIE: 108-115 MHz (115 works well)

CPU SKEW: Auto (100PS also works)
IOH SKEW: Auto (600PS also works)

Ram: 2:8 divider 1.55-1.60v (whatever your ram needs)

QPI DATA LINK RATE: SLOW MODE (this must be in slow mode when link rate is over 8000 MT/s, or my board wont post. I have verified this at various BCLKs bumping up QPI speed to next settings. As soon as its over 8000 it just flakes out. Seems the R3E's can handle this and can run up to ~8300 MT/s so they can hit 230 BCLK without using slow mode.

This is with 2x5850 running stock, Increased clocks to 900core 1150mem only gained 400 points at 1024res

Looking good, at low res you are more CPU limited than card limited. Try default res of 1280x1024 at least, or a real game demo bench at that res or higher and you should see a bigger difference.

My last test:

Rampage II Extreme
i7 920 D0
GTX280
Chieftec 650W
BIOS 1914

vCore can probably even smaller = 1.45 v

might have a problem with my seasonic psu, when i run everything stock 5 volt line reads 4.91 and 4.88 under load, but when i revert back to 4.5ghz and stress test, 5volt line drops to 4.75 - 4.70 sometimes hits 4.65v and crashes, i can stress test with 6 threads but anything above that screen freezes and have reset teh system

I read somewhere that the 5v line should not drop below 4.8v, anything below 4.8v would cause instability? Im going from memory on this, i did a couple of google searches and the numbers vary?

But with the above 4.5ghz settings i can play bc2 and any other game, but i soon as i load IBT with 8threads, system freezes, I have a feeling the psu is the culprit Its a 750watt season m12, i thought it might be enough. Running 6 hard drives, 2x5850s and 5 case fans.

[CryptiK]

Is that measuring with a DMM or software? I wouldn't trust software.

[Sanousie]

With software, you think 750watt is sufficient? its a modular high quality psu.

It was fine with a 1055t at 4.6ghz 1.65volts and that put out much more heat than this. Maybe software is reporting wrong reading?

EDIT:

I figured out the problem, i forgot i reflashed back to to the 1904 bios ffs lols, now im back on the 1504 and system is stable again at 4.5ghz, why is the 1904 so crap for? i dont get it how they can mess something up so bad, they update the cpu support list within the bios and you loose 200mhz on your oc? Go figure.

[Xel_NaGa]

I'm in the market for a replacement heat sink for the R2E if anyone still has their stock cooler and would like to sell it please let me know. Also if anyone is aware of an after market replacement I may be interested in that as well. I guess if some one has an R2E they would like to get rid of I may just buy that off of them if the price is right.

anyone have any ideas?

[headala]

Good gosh you guys weren't kidding about the 19xx BIOS's sucking. Luckily I had never flashed the 2nd chip and it was still on the original 06xx. Flashed it gradually up to 1504. More stable. Less memory problems. Slightly better headroom. OMG I really can't believe the difference!

Thanks for the post!

I'm using a 970 and I had an impossible time getting it to POST over 181 bclk. The 930 before it would do 220 bclk....

I'm seeing the same thing with the QPI at about ~8000MT/s with my 970, the board will not POST. I used slow mode as you did and the board would POST and boot into windows at 184 bclk, but everything seemed REALLY sluggish from the second the board POSTed all the way into desktop.

In addition to this, I also had to the change the CPU skew and the IOH skew to delay like you mentioned. Changing the slow mode alone would not allow my board to post over 181 bclk....

I'm trying a different 970 today to see if it's the board or the CPU that I'm having problems with.

[CryptiK]

If you are reaching ~8000 MT/s with 184 BCLK, the QPI Link data rate setting is in the middle (not the freq above slow mode but the one above that). There's SLOW MODE, then 3 frequency choices - set this to the lowest frequency choice (the one above slow mode). This should let you get to around 220 BCLK before hitting 8000 MT/s.

thanks sano . some ram test. hows this ram guys

just wana keep this thread alive
if i put my graphic card in 8x last slot what impect going to be on gaming or performance>
com on guys u all just disappiers.
sorry for my bad english.........

1-2% i guess...

there is a review on techpowerup.com where these guys test the pcie performance scaling from 16x all the way down to 1x.

oh thanks.
got any idea where to get 0077 bios for this board?

[Nuckin_Futs]

Can somebody remind me what the ES or final QS quad was for this last of the LGA775? Are the ES generally modeled after the Extreme Edition models?

[OnDborder]

Well i hit 227 bclk on mine tonight. Not too bad for a air run though. Not sure why my cpu voltage isn't showing, perhaps a bug i guess.

Killer oc.
What bios version?
Would you mind posting your bios settings?
