only 217MHz 2-2-2-5 with my Corsair BH-5 sticks?

[phobos]

It seems that my two Corsair CMX512-3500C2 ( XMS3502 v1.1) sticks only do 2-2-2-5 at 217MHz
I gave them 3,3V but a Mhz more will lead to errors in Prime. I also testet each stick alone.
Also at moderate timings ( 2,5-3-3-8) they will only do 230MHz stable.

Maybe I forgot something and anybody has an idea to improve it?

My board is a AN50R with Athlon 64 3000+ and I tried HTT speed of 300MHz without any troubles. Also my Audigy 2 works fine .
But as soon as I run the mem 1:1 it maxes out very soon.

I hope there is a way to improve it.

Cas latency to 2,5

Are you sure that theyre BH-5? sounds like CH-5..

Cas latency to 2,5

Ok, after doing some further investigation in the forums here I also found out that the shuttle doesn't like corsair at CAS 2. I'll try CAS 2,5

Cas latency to 2,5

I thought all Corsair XMS3500 CL2 rev 1.1 is BH-5 isn't it?

[Jupiler]

yes, all Corsair PC3500 is BH5.

[Saffire]

I believe only v1.1 is BH-5, rest is CH-5

Exactly true. I have three stick of 256mb pc3500 v1.1, all three of them run differently.

One of the three max out at 230fsb 1:1 2-2-2-5 at 3.1v(cannot take higher voltage than 3.1v or else error out).

I think your stick of XMS pc3500 v1.1 might have reach it max like one of my stick. Good luck though.

That's true too, I forgot to mention that.

AFAIK, Corsair PC3500 only comes in 1 rev., which is 1.1 and has BH5 chips.
The PC3200LL rev. 1.1 also has BH5, the rev. 1.2 has CH5 chips.

Yes thats correct.

[phobos]

Damn these sticks will not even do 220MHz at 2,5-2-2-6 and 3,3V.
I don't want to get back to 512MB.

That is really annoying!

But now it's time to go to bed....I'll do some further testing tomorrow.

Raise the Ras to Cas to 3.

[Geforce4ti4200]

id ebay those sticks if they overclock that bad. my mushkin level II would only do 220fsb, so I sold it and bought corsair value, does 220fsb also and cost me half the price. 2-2-3-11 timings, only lost 400 marks, most of it single channel

[FatesWarning]

Hmm, one thing I have never tried is raising the northbridge voltage is that vdd. How do you know if you need to raise this for overclocking? I have just been rasing vcore and vdimm.

[Boogotop]

that was pain for you guy....my Mushkin PC3500 Level II 2x256mb run without 232mhz 2/2/2/5 @2.8v

indeed

2x512 corsair pc3500 c2 1.1 does 220fsb 2-2-2-5 @2.9v with my Abit nf7-s. Could be the shuttle causing problems and not the memory sticks......

[eva2000]

about tight on my unmodded AN50R tried a few 256MB XMS3500C2 at 2.9v vdimm all do between 220-230mhz 2.5-2-2-6 with my A64 3000+

it isn't the memory that's the problem as same 256MB XMS3500C2 do 240-245mhz 2-2-2-6 at 3.2v and around 220-233mhz 2-2-2-6 at 2.95v on AI7

[phobos]

I will try RAS to CAS 3 now and if that doesn't give me nice speeds I'll try to max them out in my friends NForce 2 board

[phobos]

Unfortunately I had the last pair of Mushkin Level II 256MB sticks from a shop here in germany but those sticks were not ok. They needed 2,9V to to run at 200MHz DDR. So I had to send them back. Because it was their last pair they could not give me a warranty exchange and I just got my money back.

[phobos]

Seems like 217 is the absolute maximum for the memory on my board
Prime errors out on everything >217MHz, no matter what timings I use.

[macci]

The Shuttle board doesn't like to OC w/ every kind of BH5.
Mate has 2GBs of HyperX ram and only one stick (KHX3000/256/Single sided) will overclock properly. Doublesided KHX3000 wont OC much at all on that board even thou it can do 240++ on other platforms (K8N, P4C800, IC7 etc).

[phobos]

But I thought many people here are running the Shuttle with BH-5 and tight timings >240MHz. Am I wrong?

[Diablo II]

just cases... shuttle + bh-5 is a very bad combo

[phobos]

What should I run instead of BH-5?
