Asus CHV Formula overclocking

[chew*]

I've had some problems with cold booting this board below -80 C. Warm resets are okay, but after hard reset I have to warm up - any ideas what that might be?

It also seems to have the same "tiring" syndrome Crosshair III had. After 2-3 hours it won't bench at the same clocks anymore, but that might be related to my insulation method and something on the board freezing too much.

This board was tuned to run flat out even on LHE and i have run it for 7 hours+ non stop on ln2 without a hickup ( it's nothing like previous boards, this you can freeze ad forget it ), check your insulation or settings pertaining to memory

Hmm, memory... got to try PSC and hand tune settings next time. Thanks for the hint.

Crappy pic but my good camera is in Austin TX.

Anyway got some time to play seeing as wife is off to work already.



Actually tossed a rig together in living room for pretesting for my second build. Plan to mirror my sandy bridge rig for the most part hardware and settings wise or at least come close.

Here's where my sandy rig sits daily, it's obviously stable



And here is where the mirror image BD Rig is sitting now.

NB @ 2600 for those that are curious.

i faced this once then the second time i cold boot at max pot temps it was fine, i'm guessing socket contraction/expansion thingy, if you can repeatedly repeat it then it sounds more like cold boot, if not it sounds like contact
some old issue, gulftown, gtx580, lot of times thermal paste gone bad.

nice Chew*, hope, u will work at some nice results. Do u have only FX 4170 now?

He is using a FX-8150 in single core mode (4CU/4C).

Any word on the CH V vs other 990FX boards performance ? I saw a post of OC forums, but some of them results look so out of bounce that I can't give it any credibility.

[FlanK3r]

thx, I dont seen it , now yet at screen

The results are messed up & most likely done with different clocks.
SuperPI 1M calculation gives that instantly away.

[Leeghoofd]

yeah Wprime 32 is also way off.. no idea what he was doing... maybe he ran everyting at once :p any update on 9911 bios ? My asus rep is sloooooooooooooooooooow again...

Update?
That bios was compiled two days ago

[FlanK3r]

try some diferents, practice some files to rar etc...Here u will see diferences between Thuban and FX. Or megatasking, ework in pohotoshop, video creation. I think, here is the "big" diferences between PII and FX. Thuban was better for benchmarks as superpi or wprime, FX is better in practice software.

I'll hopefully have it tomorrow then... if the Dutch boys are in the office...

I have it leeghoofd, hit me up on msn, your not gonna like my findings though.

[Leeghoofd]

Got it already mate from the Asus rep... will test tonite, will talk about your findings tonite on MSN...

Quick Vantage cpu runs..

0051 cpu fan error on boot up?

hitting reset button fixes it but

any ideas

set bios not to hault on errors in boot options.

While i was doing some game test scaling i fooled around with this chip and some interesting ram modules.

All this is suicide on air just feeling board out.



Yes the mem voltage is real, only stock voltage and loaded PSC and 4gb module settings to test board out, I hit a CPU_NB ( wall/air ) at the higher clock speed........

[The Stilt]

Is it doing the same with 1:6 divider too?
I´ve tried with a couple of CPUs I have, they can´t do much over 2500MHz stable because of the NB.
Haven´t tried with other dividers thou, maybe it is a DRAM PLL divider related thing on K15 too.

The higher straps didn't feel like real speed to me, nor did the speed of ram even show up in cpu-z.

When i say didn't feel real i mean it was like 6-9-6 at 2200 at stock and not even this set is that good

[G.Foyle]

Same here - I'm trying to compete in max validation for this month's HWBot compo, and NB wall is stopping me hard at 2828 MHz. Every divider other than 1:6 needs NB even faster for the same mem speed. 3:14 seems a bit better for CL8 though, as long as I'm staying away from high NB MHz.

what BIOS is now the best? Still 9905?

I just saw this in another thread; BIOS 9913

9911 is the most recent and advanced.
