MaximusIV-Extreme Thread

[miahallen]

I have finished my Maximus IV Extreme build...Flipped the switch yesterday and...all was great.....except one issue.

The Revodrive X2 that I have in the bottom PCIe 4x slot is only running at half speed (400MB read in ATTO) vs the advertised (740MB Read). Will not be back in town until Friday SO I will have to wait to start overclocking this beast until then, but was hoping someone might have some ideas why it is only running at half speed...I have been trying to think what the cause might be:

1.) PCIe Lanes are maxed??
2.) Bios issue with bandwidth in the 4x slot..

I looked into the same issue in my UD7 VS MIVE review here:

Thanks...Great article!!

My issue is that I am running 3x gtx580....so the Revo can only go in the 4x slot....so far no updates from Asus or OCZ and for the time being I have replaced the Revodrive with a 4x Raid-0 64GB Micro Center Sandforce (Adata S599) drives...the result is amazing...

[MikeMK]

Ive been wondering the same thing. About to start my build in a couple of days

I know it doesn't solve your problem...I just wanted to share that my small investigation confirms your results

[MikeMK]

Hey guys, got my board up and running now and just having a quick play. LinXing 4.2ghz as wee speak. Have a couple of questions about bios options that I cant find lol. Firstly, seen a number of people recommend turning S3 off but cant find it. Secondly, Ive been looking for LLC but again I cant find it anywhere?

EDIT: wouldnt mind a bios recomendation either... currently on 1090 BETA which is the most recent I could find

[MikeMK]

Well, i found the LLC in the end! Anyhow, here are a couple of pics of my M4E build:

[stasio]

BIOS 1101 is out.

[cstkl1]

hmm new bios kindda suck on one thing
higher rtl and higher latency

checking now to see whether can go higher dram clock

so far 1090 is the best for me.

[cstkl1]

hmmm

RTL 35/36 2250 7-10-7-27

Bios 1090 VCCIO 1.075,VCSSA 0.975
Bios 1101 VCCI0 1.15 , VCCCA 0.925v

eh

conclusion to non b3 ppl
DONT FLash to this bios since u cannot roll back
further testing on this official bios

still preplexed.. looks like the imc got stronger and rtl got weaker.

[jcniest5]

Here in uk! http://www.overclockers.co.uk/produc...d=5&subid=1906

Is the board going to be the exact package as the ones being sold in the US? If yes, I wonder how much shipping charge to the US. I want to place an order! It seems M4E is the OCing King right now for SB CPUs.

Just checked and they don't have the M4E, though...they do have almost everything else.

SLI GTX580 is not working at PCIE X16/X8_1 and X8_3 but it worked on X16/8_1 and X16_2 (NF200)
I'm using Win7 x64 SP1, BIOS 1092 & 1101
I don't hv any other PCIE card except for these GTX580s, unused PCIE slots are switched off but seems not helpful though
Freshly installed Win7, GForce 263, 265, and 266.

Not work how? The second card doesn't show up or not able to run SLI? PCIE X16/X8_1 and X8_3 are the slots I used for the GTX 570 before going with triple cards and didn't have any issues.

1st Round of Tweaking Reduced tRFC etc

[st0ned]

So in your opinion, after some tweaking 1001 comes ahead of 1090?

[Leeghoofd]

RTL means?

Round trip latency Alex... was first in the X58 biosses...

Good work CSTKL1 amasing job !

lol 3rd person now lol that knows that doing the above wasnt easy.
ty.

but basically can go higher stable thanks to the sham and the engineers

[st0ned]

Where can RTL be adjusted?

[chew*]

For those of you using hypers, I highly suggest red slots for low vdimm operation. I might add this is by no means a piece of cake.

1.76vdimm, red slots, bandwidth booster off ( no noticeable gains on other than less stable )

I have requested some more option in bios as far as ram goes, see how much better we can get the effec if possible.

Them speeds aren't even easy with Powerchipoes (unless you have an amasing kit) Can't get anywhere on the other Asus boards in the lineup with the retail 2600K chip... working on it...

[Ghostleader]

RTL means?

Round Trip Latency


Edit: I was to late

[Alex-Ro]

Can you guys post full block of memory related and voltage related options in maximus bios?Thnks Currently contemplating a move from my biostar tp67 to maximus and trying to figure out if it's worth the price(triple than the biostar)

its not a dram issue per say.
but the other asus lineups wont be able to do this on linx, prime should be not a issue.

btw my rams are just above average. the best of the best are the 2k c6 6gb kits pairs.Mine is somewhere about the same as the 4gb kit pairs or 2400 c9 pairs.
Dunno why ppl dont read some of the stuff ive been writing about hunting older psc kits that are cheaper and are amazing.

the beauty part about p67. all results are reproducible on any proc. only diff is the vcore and cpu speeds
