safe voltage for BH-5

[crunchie]

Wondering how far I can safely take it?
PC3500 currently running @ PC4000 (DDR500) 2-2-2-5-1T with 3.5 volts.

[Nebulous]

WoW :eek: 3.5v is pretty much the limit with active cooling. I personally ran mine @ 3.2v.

[ou_phidelt]

wow, BH-5. I haven't heard anything about them in a long time. They were all the rage when I first go into this game but missed the boat by a couple months and had to settle for BH-6. For your question though you are at the limit and wouldn't go any higher. Make sure you have some air flow on those puppies.

[crunchie]

No worries :). I have a 120 fan blowing straight on them. The board is out of the case too. Got the jumper on the board set to where I can pump up to 4v into them :D.
Might see what frequency I can get @ 3.5v.

[Quailane]

Yeah, 3.5 volts is perfectly safe. I ran my CH-5 at 3.4. Gotta love those DFI boards using the 5v line for the memory. Don't go over 3.7.

[crunchie]

No probs :)

[Bo_Fox]

There were some review sites pushing it to the max, 4.0v!!! Come on, do it!!

I'm pushing ya! ( just kidding).. :D i dare you!!!

[crunchie]

lol. I don't want to blow the board as well as the RAM :D. I've got an opty 165 that I've got running @ 3150MHz on this board and would like to keep it that way :)

[HousERaT]

What sticks do you have? Are they the old school BH5 or the higher binned CH5? The old school BH5 is a lot more durable. I ran mine 3.4 and benched as high as 3.6.

[crunchie]

Old school OCZ's.

OMG, what voltage?? Yours is definitely a golden chip!

All stable?

[crunchie]

1.472vcore :) :). Stable enough for a SuperPi run. Bit more vcore would bring it stable.
This thing will run 2800MHz stock vcore and 1.375 @ 3000MHz :). Not bad for an 1800MHz stock frequency cpu :).
It's back under air atm until I get some more W/C bits together and I can play a little more.
Did a quick run again the other day @ 3150MHz with my 9600 zalman, but it's not quite up to the job :).

Wow, man.. certainly a golden chip!

Anyway, is the BH-5 only in 512MB sticks, right? And you only have 2 of them, correct?

Yeah, that's right. 2x512 modules.

Running the Opty naked too so I can get the extra bit of cooling :).

A shot of a run a couple of minutes ago.
74623

[Bo_Fox]

Damn, I went through like half a dozen Opty 170's that were either CCBBE's or CCB1E's and the highest I could get was 2.9GHz Prime95 stable. There was one CCB1E that did run at over 3GHz stable, I killed it when I tried removing the IHS by accidentally hitting one of the capacitors/resistors with an exacto knife. Damn, I should've used a razor blade instead!

3.6v with active cooling for benching on bh-5. I killed a couple of sticks, but I didn't care cause I had some badass tccd from SN that did 620 memtest stable and 610 windows stable.

[WonderingSoul]

That's pretty sick.

I have gotten some nice clocks out of the famous XBLK's TCCD, 600 @ 2.5CL, IIRC

[Bo_Fox]

One thing that I find funny is how there were 512MB sticks from *many* years ago. It took maybe 2 years for 1GB sticks to come out, and then another 3 years or so for 2GB sticks to be released.

We're still not seeing 4GB sticks being released into the mainstream this year.

The complete opposite happened for flash memory. A few years ago, there were only 2GB jump drives. Now we have 32GB and more already, and 8GB are dirt cheap.

I guess some things just plateau seriously.. like CPU's and hard drives during 2005-2007.

Yeah, I have a dual channel set of TCCD's that will do 615 Windows stable too :). OCZ's.

Am maybe going to see if the BH-5's or the TCCD's are the better benchmarkers at their rated specs.
PC3500 2-2-2-5 and PC4800 3-4-4-8 respectively.

[freeagent]

awsome!

newer tccd's didnt like voltage did they?

[crunchie]

Not many of them do. Mine are on 2.7v to reach that frequency.
I certainly have more fun OC'ing my 939 system than I do with my 940BE :).

PC3500 currently running @ PC4000 (DDR500) 2-2-2-5-1T with 3.5 volts.

I've run my sets of Mushkin PC3500 @ 3.6~3.7 V 24/7. 270MHz, 2-2-2-2-x. ;)

I remember corpsejockey was running BH at 3.65V at the same timings. You need a fan or two over the RAM though.

If you ask me, as long as you can keep the sticks cool (i.e at ambient) it will take as much juice as you feed it (even 3.8~4.0 V).

Cool. Thanks for the links :)
