I'm at 2.9 on air 1.5vcore, with a 3200+.
Try to take ur memory totally out of the equation, since it doesnt seem good and could still be giving crashes, unless u'v alreayd tried.

@Espen
I have a neo2 and I have lots of issues with my ram, with the cpu underclocked it does 295mhz 2.5,3,3,7 and into the 310+ with 2.5,4,3,7
But when i try to up the cpu at about 275mhz on the ram I start geting errors and nothing, I mean nothing fixies them at 274 its fine 275 errors, any timing or volts or anything doesn't help really hope this bios is the answer.
Ram it ocz rev.2

I'm in the same boat as 4rory, the slightest increase in clockspeed and i get a wall of errors that voltage can't fix.

My RAM is total crap dude.... It cant go over 210 Mhz :( WOW.. I would never buy corsair again. They suck... I had a chinese Value RAM that I bought for 40 bucks.. a 512 stick with crappy timings like 2.5-3-3-7 and I was able to go over 230Mhz... Now this fancy stick has a platinum heat spreader and it cant even do 210!!! WOW GOOD JOB CORSAIR.....

heh, that's pretty bad ram. I had corsair XMS before, i thought it was good stuff until it crapped out at 220. This TCCD stuff is so much better, it just keeps scaling.... i'd like to try new BH5 but i can't supply enough volts

Yep.... had a 3200 XMS v1.2 (CH-5) that wouldn't do 205Mhz...

I've been working an OC of a venice lately. Here are my results but I need some help.

260 x 10 @ 1.53v according to cpuz
Ldt 3x
tccd 3-4-4-8 @ 2.9v
all other voltages stock.
temps 40c after 17hours of prime95

So all is pretty good at this point. So heres my question.

My memory can take 315 fsb at same timings and voltage so I tried droping the multi down to 8.5 x 300fsb. but I never get past the cmos check. when I drop themulti even more to like 6 I can get into windows and prime for as long as I let it run which was like an hour. Not sure if it'll do more.

What do I need to do if I want 300-315fsb x 8.5. I've even tried losening the timmings.

The cpu runs at 2.6 and the mem runs up to 315fsb stable seperately but I can't get these numbers to meet and run together.

The mobo is dfi nforce4 ultra

x.5 multiplier don't work very well

I'm looking in to by a venice. Is ther a preferd steppning I need to look for ?

well 9 x 275 didn't work either. do you have any other suggestions?

Week 17 seems to perform very well.
Maybe this topic might help you :

good old BH5 + Venice ownage: 30sec @ 2700mhz

can do 2850mhz easy with stock cooling. 2700mhz @ 1.44v primestable

edit: and 25k 01 on 6600GT low clocks

Week 15 too :D

chainhoe, BH-5 voltage ?

Does anybody here have any indepth knowledge of htt and ldt functions and some of the other advanced controls on the dfi mobos? The cpu runs at 2.6 and the mem runs up to 315fsb stable seperately but I can't get these numbers to meet and run together.

yasoumalaka, nai ola

Join the club, ive been after this info 4 ages, ive even started a poll related to this.

http://xtremesystems.org/forums/showthread.php?t=63998

If u find any info please PM me

yia

will do. I like the board despite all the confusing bios options. At first it wasn't even stable enough to install windows. I had to change the timmings.

Now I am stuck using 2T only with 2 sticks (was on 2t for 4 sticks before)...
There must be something I am missing.

Hey Jin,
Are you using the regular or 5v jumper option on your board? If so, then test out your Mushies in another board to see if they'll still do 1t. I say this because people are finding out that a lot of sticks of UTT are dying due to excessive Vdimms on the dfi......

ReelMonza, BH5 @ ~3.8V (3.7 from bios, DFI NF4)

Everyone seems to have problems trying to get there memory to perform as it can on these core, im praying to god a bios update will fix it, tho i doubt it, what can and can't be fixed with a bios update?

They still do 1T :P Besides, on this venice, I've only been running 3.2v so far... :P I had my 4 sticks of Blue died on my not too long ago with 5v line. Haven't used direct 5v line since than.

why you using 5215?

is latest

I tried 9x288 and it still woudln't boot. There must be some setting I need to change somewhere in this jungle of a bios.

Well here is my max stable 3000+ Venice O/C. Ram walls at 310MHz a little shakey stability wise, and one
of the sticks in the 2x512MB set is bad, so I am looking for a replacement that can handle DDR640+...

Any suggestions on what I timings I can tighten (see screenie) would be most appreciated.
Also, what should I consider the maximum core voltage? Temps aren't a problem.

Welcome to the forums! :D

Nice OC and settings!

Could you take a screenie of A64 Tweaker? I'm trying to find out why I can't run both sticks of my ram at once.
I'm pretty convinced one is less capable than the other but I am somewhat reluctant to get another GB set not knowing if it will work or not at 9x300. Although I am very tempted to get this amazing stuff here.

Hello everybody!!!!

So far with 3200+ venice i'm at 2650[10x265] stock HSF default Vcore!Prime stable

Tried 10x270 but after 2 hours stressing ,windows locked and had to use reset switch...:mad:

What do you think about this chip?Is it good or bad??

Also does anyone have any issues with unstable vcore on Giga K8NS-ultra?CpuZ readings are jumping from 1.392 to 1.44!!! :stick:
