Maximus Extreme - Results/Info/Bios

Anyone with BIOS 1001 and 45nm CPU over 490 FSB? i've tryed 6 CPUs and non do 500 FSB (1 QX9650 and 5 E8400) i'm really stating to think about motherboard / BIOS for this issue

hiya metro it seem 500fsb plus on the extreme is not as feasible as on p35 boards, i have also tried 3 all stop at around 4600mhz, 500fsb stable but over 511 ,like 512-513 fsb very flaky, the only thing i found that helped to bott at 500fsb was disabling transaction booster and setting the relax level to 3 or 4 , then once in windows using memset to lower the performance level again, i think the only way over it is a new bios revision, i have benched 05,03,aquamark at 4603 which was 512 fsb on the e8400 and 3d06 at 4575 mhz (509fsb)

QX I can bring to about 470 E8400 to about 540, but needs VMCH to do so

500 fsb was no trouble on my board with E8400:



Max bootable was 550.

Max on qx9650 on this board for me has been 465.

[GLENBOY]

mike which bios you use and what mch volts, and what would it do benchmark wise at over 515fsb superpi,3dmark , aqua etc on the 9 x multiplier

Aivas nice to see you, whats the max fsb using the 9x multiplier , it seems that 500fsb stable but over 510 is flaky, i am really talking about the max multiplier, thanks

i have completed 3dmark06 at 508fsb (4575mhz) http://service.futuremark.com/compare?3dm06=5040734

3dmark05 at 514 (4626mhz) http://service.futuremark.com/compare?3dm05=3954398

and aquamark at 517fsb , but any thing over 500fsb it was flaky i have had 2 e8400s and 1 e8500 and they have all topped out at 4500-4600 irrespective of voltage but some of the p35 board owners have had like 4700-4900 mhz, its not a big difference but i'm wondering if the internal memory timings on the northbridge are a bit tighter on the x38 boards than the p35

Big hello's to everyone!! this is my first post on Xtreme Systems & this forum & particulaly this thread are just great!

I am using a 2 gig kit of Super Talent W1600UX2G7 CAS 7-7-7-18 with my maximus & would like to run my Q6600 @ 3600 with memory running @ 1600 cl7 the very best i can achieve is CPU 3600/ MEM 1440 cl9 it's like nailing jelly to the ceiling i have spent hours altering & tweaking voltages in the bios (904)
but i simply cant reach my target could this memory be faulty or does the maximus not like this memory?

That is what i use and got been getting good memory overclocks

hiya metro it seem 500fsb plus on the extreme is not as feasible as on p35 boards, i have also tried 3 all stop at around 4600mhz, 500fsb stable but over 511 ,like 512-513 fsb very flaky, the only thing i found that helped to bott at 500fsb was disabling transaction booster and setting the relax level to 3 or 4 , then once in windows using memset to lower the performance level again, i think the only way over it is a new bios revision, i have benched 05,03,aquamark at 4603 which was 512 fsb on the e8400 and 3d06 at 4575 mhz (509fsb)

Thanks Glen, i tested my E6850 that does FSB 555 on P5K3 Deluxe and the max i got on this board was around 517MHz benchable.

I use transaction booster at 2 or 3 will give it a try to disable it.

Do you guys favor the white or blue mem slots when overclocking?

Depends on memory i've tested 3 good memory kits one like the white ones a lot other did better in the blue ones

QX I can bring to about 470 E8400 to about 540, but needs VMCH to do so

Hello Mike,

Could you share your settings? on bios 905 i could do 475 with the QX9650 tryed almost everything i could read/think of to get 500FSB but was imposible.

Now on E8400 i'm really disapointed and starting to think that is a board issue or i'm overlooking something, i could use your wisdom with FSB 530-540 for now im happy.

Regards

I will try to put up detailed settings later today, but I doubt that you overlooked anything. It's my second day on this board and I only ran 1001 so far. I am getting in another ME next week and I will be able to tell more about variances between individual ME boards.

From my memory NB voltage was about 1.76V, VFSB around 1.55V
Transaction booster was enabled and at 3, BUT Static read/write both DISABLED.
Vpll around 1.75V, but again this is all from memory. I'll get more detailed later today when I plug in the E8400.

QX9650 I tried very hard to get to 500FSB as well - no go ( no clue what the max FSB on my chip is on another board)

One thing is for sure X38 is def. not the right board for E8xxx FSB clocking 965 would do worlds better in terms of FSB

@Glenboy - I'll post some 9x multi benches later as well will have to spend some time with the family first

EDIT: One thing to do when switching between CPUs - make sure to clear bios / load default settings and start form scratch with bios settings

Quick question...

Has anyone here removed the stock cooling to replace thermal compound, if so, did you have any issues ?

If I remember correctly I had some issues trying to remove the stock cooling on a Formula SE as the heatpipe seemed like it was welded to the northbridge.

Thanks in advance

I have benched 547mhz spi1m , and also orthos stable for few mins at 525mhz.
All other benchmarks (3d's , wprime) at 535+ . Try transaction booster disabled 1 , static read : disabled , delayed write : disabled . Mch 1.85V or more if your mb can handle it.

Thanks, seems to me that Asus might be doing somethign wrong with BIOS on 45nm, i changed to my P5K3 Deluxe and could do easily FSB 530 if i disable transaction booster but this makes Super Pi times on 2M a good 2 seconds slower. If i leave it on i top around FSB 500 on P5K3 Deluxe, didnt try to disable Transaction Booster on X38 because clock for clock it sucks then.

Might just do that and test again.

Metro.cl- the key value for me to get the FSB going were both Nothbridge and Vfsb voltages. Obviously with the E8400 we're running into 2 walls - the CPUs and the Mobos FSB. I tried the E8400 on phase only managed to get up to about 555 FSB not sure if it was the CPU or the mobo - probaby both. Vpll had hardly any impact for me - 2V+ only did harm.

Thks will have to try your settings, but i was with that Vcore and in Miami, what kind of air cooling are you using?

Never tryed such high clocks as you use maybe my problem is that i became a chicken

I am a chicken too when it comes to running 24/7, but for a quick bench here or there...

Actually I live in Vegas now - and it's a bit cooler..at least at the moment, but not much longer...

Vcore - yikes ,well my CPU is a dog - I had another E8400 before that did 4.75 with 1.65V and a max FSB of 575 on a Maximus Deluxe, but it was my first Wolfsdale and I thought it was not good enough ( hoping for 600+ ) and put it up on ebay - too bad now that I realized how good it really was.

This E8400 really scales only with massive Vcore - had it up to 1.9V (air ) and still kept going up clockwise - obviously I only ran 1Ms and nothing to really stress it ...and it still runs happily

Another thing to look into is SouthBridge voltage - not sure if it truly has any impact, but might be worth checking out.

CPU GTL might help to lower the vlaue depending on your CPU, I had more luck with another CPU using the 0.53X setting
