Max out for the BH-5, DDR575,2-2-2-2

[KuRi]

Seen any 8.6k Sandra buffered, with 2t enabled lately?

EDIT: thanks onepagebook, sandra shows it wrong.

[TEDY]

KuRi it's 1T :>

[Revv23]

god this makes me want an A64 sooo bad...

i have 2x512 bh-5 and i have 2x256 bh-5 and i have one stick of bh-6 512mb and i dont have a single rig that can run over 240 FSB

im hoping once my new psu comes in ill be able to get more juice out of my infinity...

Sisoft always read that CPC incorrectly
2t can't get over 90% efficiency

then u r saying that in 1t u get over 90 % ?

[Onepagebook]

at lease over 85% most of the time

[EnJoY]

wouldn't a higher tras provide better bandwidth scores? I'm think that running 2-2-2-2 timings over say, 2-2-2-5 may actually hinder performance as the ram does not have enough latency for it's other timings to work properly. Hence you may be wasting cycles.

i get on the asus P4C800-dlx 72-73 %

or what u said is only for AMD's ??

[REDKEN]

but will an a64 survive that vdimm for long?

Hi guys!
I was wondering the same question. I'm and Intel user and I'm not up to date with AMD CPU's as of late, but I'm planning on getting an A64-fx system by January or February when the new stuff comes out. I'm researching now.

I have a pair of BH-5's that can do 250 @ 3.4v 2,2,2,5 and a DDR Booster. I had read (a long time ago before I bought my current rig) that there were A64'2 dying because of high voltages. Is this still true?

Thanks for any info you guys can give me

[jagare]

Were any mods required to get up to 3.9v with the booster + Neo2? I'm wondering because I'm getting a DDR Booster soon and I have a Neo2.

[STEvil]

New revisions dont seem to be suffering from the same problem that the old clawhammers did, REDKEN.

It could have even been a motherboard issue..

Nobody is really 100% sure

Wish we could get an official word from AMD on what the problem is and if they have fixed it or not..

[Jaan]

Onepagebook, try CL1,5
my best is 275MHz@3,7V (1T, Dual Channel)

3200+@2755Mhz
Hype6
MSI Neo2
arcooled system

[Onepagebook]

yup thanks Jaan, I have tried around 277 for 1.5 w/o any problem but bench about the same w/ CL=2

that was only an issue with the shuttle AN50R, afaik

Thanks for the reply. So, right now people are feeding as much vdimm to the boards as their particular RAM can get? (just to be very sure ) In other words I can feed 3.6v to my RAM (which can take it) and not have to worry that my CPU is going to die, right?

Tanks for your reply too blinky!

[Malachia]

onepage can you told me how much in fsb tours rams get at 3v???

What kind of cooling do you have on your BH5?
Mine don't go any further than 260mhz 2-2-2-5 @ 3'7V with an 8cm fan blowing on them

Maybe your BH-5 ic's CAN'T go any further. Try to give them 4v and try.

Your Processor was a northwood, right? By air you may have troubles to pass a determined number of mhz/fsb, who knows... (vamos, q tu micro puede q no de para mas y aun espero mi ys-tech y el adaptador xD)

Besaid spotted!
I've got a 2'8C M0 capable of 14x250 @ stock volts.
And well, the OCZ DDR Booster won't give me more than 3'7V, duuno why
I've got 2x256 Corsair XMS3500 V1.1

I'm using 2-70mm fans right on top of the RAM via a custom bracket I made and have 2-120mm fans on the side of my case feeding the 70mm's.
Is that 3.7v used 24/7?

[wambas]

Nope, 3'5V for 24/7 240mhz 2-2-2-5

[X-GeN]

Nope, 3'5V for 24/7 240mhz 2-2-2-5

could that chips be bh-6

[wambas]

could that chips be bh-6

I thought all Corsair XMS3500 V1.1 were BH-5

[HaLDoL]

hey Jaan,

here's the same run as you did, only difference is sc (s754) and better timings. dc makes alot of difference. Also aircooled btw

[Evil_Spork]

why does your screenshot say gskill ram, and your description say mushkin bh5?

[Fewture]

That is one sick overclock.. My god..

I have some 273MHz BH-5 (on NF2) here somewhere. You make me wanna buy an A64 rig just to test the ram on it
