BH-5 over 5volts

[sang]

2-2-2 for something like >DDR600 speed.3D bench.I think its doable.
im sure screenshots do exist at this high frequency but im not sure if the chips will not get hurt for something like 15 mins. at this voltage.Ofcourse,properly cooled.:)

[skate2snow]

2-2-2 300MHz is pretty much a dream ATM....

And BH5 might not be affected....

[[XC] moddolicous]

it would have to be REALLY good BH-5. I think the highest I've seen was 275 2-2-2 somewhere on these forums. Properly cooled would have to be water or something, I dont think a fan or two will cool it enough.

[[XC] moddolicous]

hmm BH-5 @ 300HTT 2-2-2-5 with wc and waterchiller :slobber:
I could see it happening. As u said the ram would have to be watercooled and waterchilled. This would be amazing if he could do it.

[HARDCORECLOCKER]

:D This is @3,9 Vdimm and a 120mm fan on it:

http://de.geocities.com/hardcoreclocker/Corsair275.JPG

Tried up to 4,1 Vdimm but no improvement anymore, think the BH-5 won't get damaged but are maxing out of performance there on air cooling.

Try to put peltiers on it !!!

:toast:

[Sup3rman]

I'm not an expert but but i think it would take less than 4.5v for BH-5 @ DDR600 2-2-2
if you can cool it.

My guess, BH-5 would do DDR600 if water cooled

[[XC] moddolicous]

thats my guess also, but we have to wait for someone to try it.

[Sup3rman]

ultron5 did 286MHz 2-2-2 with Kingston PC2700 - 512

[skate2snow]

Watercooling them wouldnt help much..... I think it is Bowman that kind of put them under phase change, and he didnt even gain 3MHz.... I'm not sure thought....

It would help keep them alive...

[HiJon89]

I saw a thread by BigToe I believe that said with the DFI SLI board his BH-5 clocked 20Mhz higher than in any other board he used, maybe this is the key to DDR600 2-2-2?

[Zeus]

300MHz 2-2-2-x would be awesome :slobber: but what can't be done with 3.8-4.0V can't be done with 5.0V either imho.

Maybe a very very good 256mb stick will do it after burning in properly.
Keep in mind that all 8 chips on the module has got to do this, if one "only" does 290MHz or so the stick refuses to run at 300MHz

One of my 2 sticks of HyperX has one bad ic, whenever memtest throws errors, it's always in that same certain 32mb span. :(
More voltage doesn't help. :mad:

Looking through the SS I have saved on my HD, I see 280, 280, 335, 289, 297, and 300.. All at 2-2-2 timings

I personally get 270 from my bh-5 with 3.6 volts..

[bias_hjorth]

I too would love too see the highest bh5 stick ever posted - Without using 0.5 or 4x multi.

Plz lets keep the language civil in any way possible :)

:D SRY - Ya're right bias, but I never ever heard of any RAM, even with 5 volts, doing 335 at 2-2-2-x !!!

Seems to be very suspicious - or did I sleep to long ???

[HiJon89]

You mean shipset is bottlenecking the BH-5 ram?
Not sure, here is the thread:

No problem :)
On the ontopic side I too find it very suspicious. But I am looking forward to being surpriced :)

[bachus_anonym]

Personally, I don't think that stable DDR600 6-2-2-2.0-1T is doable with BH-5. Maybe with 1 stick of 256MB one cuould appproach DDR590 but I don't think it would be stable enough to run set of demanding benches on it.

muhahaha, :D :D :D :banana4: i did 295fsb 2-2-2-5 :D 3.9v NOT stable ust print screen, cant show it now because its on my s-ata hdd and i dont have a s-ata mobo right now, will try later with dfi when it arrives, what do you want max stable or ust max print screen?

[HARDCORECLOCKER]

:D Think we're talking about STABLE - my 275 are stable and of course for just a screenie there is some more in it..............

:toast:

[[XC] moddolicous]

it just has to be stable enough to get a screen shot. I would like to see it run 3dmark2001 at around 285/290 2-2-2-. Has any1 done that

[eshbach]

not stable, but i got 2-2-2-10 1T on 4.1v

[bachus_anonym]

274x10 is all I could do as far as max 3dmark2001 stable run....
At 272x10 I could run pretty much any bench... Everything is under a link in my signature....
I think that Onepagebook hits DDR594 with his set of Mushkin but as far as I remember it was either a screenshot or SuperPi 1M...

[bachus_anonym]

@eshbach,

if you can get a screen-grab of DDR600 1x256MB - then what is the max stable for this stick - I mean some major benchmarks...

´will try stable with the dfi, IF it can deliver above 3.2v..... :stick:

How did you cool the ram?

[[XC] moddolicous]

Also, what make was the ram?

[saaya]

ive seen above 300mhz 2-2-2 benchable, but its not vdimm dependant!

some bh5 will already stop scaling above 3.3v and more vdimm barely does anything or only crates instability.... its not just more vdimm=higher oc

[sang]

from cpulloverclock sig: DDR738@2-2-2 If he got a screenie at this speed i think DDR600 its 3d benchable.But how many volts for that insane speed ???Ofcourse,with only one 256stick.But its enough for a 2001 run. Just strap a >2mm thick wire from 5v atx conector to #7 pin dimm slot.And this way you bypass the dimm Fet's and Vrm.But a quality PSU its required.
Bigtoe,are u sure abot that? Have you tested in this way?
Maybe BH-6 will survive at 5v "treatment" couse its an older technology?!
My Mushkins 2x512 were 3d benchable @ 277 with 3.7V in a dfi nf3..Well,ill go for a 5v feeding process but first i have to find a good 256 chip.

[sang]

saaya: if there is not vdimm influence then must be cooling.U got a link for >300 bench ?

[eshbach]

Also, what make was the ram?

RAM was Mushkin Level II 3500 256mb.

cooled with nothing more than an 80mm case fan. no heatspreader.

[eshbach]

@ eshbach.

now i know why you want your cascade so bad.. :p:

that is just sick..congrat's on those mem speed's with the right chip and you'r cascade you could realy tear it up.. :toast:

ill send out you'r cascade tomorrow or the next day. ;)

sounds excellent :)

i think i can get through 3dmark at 285.... should be good.

[Zyklon5]

BH-6 is the way, or we just have to check voltage scaling on those WinbondUTT chips. If i get my new mobo i'll try some outdoors -10 degrees action on 2*512 that did 275 @ 3.6v.

bigtoe have you tested OCZ VX for brief periods with higher voltage ? 3.6 - 4.1 ?

[Micutzu]

I think that was 275 2-2-2-5 1T at 3.3V IIRC :D

[_Eduard_]

DDR2 should be able to do that soon, there is already 2-3-3-7 ddr2 @ pc5200, so I guess 2-2-2 isn't a long way after all

275 2-2-2 @ ~3.35v (http://webpages.charter.net/conrad-digital/Rabbi_NZ/8x275%202-2-2-10-1T.JPG)

no, i think it was tom holck or mricee... not sure... its been quite a while... maybe you can find it here on xs using the forum search function...

you mean ddr2 at 3-2-2? i cant imagine ddr2 running cas2, i thougt ddr2 is incapable orf running a cas lower than 3?

Single channel BH-5. But still pretty impressive IMO.

OCZ Hall of Fame (http://www.ocztechnology.com/aboutocz/press/2003/78)

[Rabbi_NZ]

That memory is running at 284 MHz, not 310 MHz... impressive non-the-less tho

[[XC] moddolicous]

I remember this. Yea, he's running a half multi, so it doesnt count, but it is still prtty good.

[jjcom]

So did I, can anyone confirm this? I thought the tighest it could run was 3-2-2 currently...

5volts throught BH-5/6, CH-5/6 chances are, will kill the RAM before you can get any where with it. Think about, 5v is alot for DDR RAM

And it will KILL your cpu aswell!!!!!

I know someone gave 5v by accident to a pair of 3500eb and fried them and a FX53 in the process!!!!! :stick:
