Who here runs 2.9 vdimm?

**kpxgq** · 08-02-2003, 02:13 AM

upped my vdimm for the first time to 2.9... i just got into windows at 254mhz fsb at 2-4-4-8 timings.... i heard this could fry your ram though

shouls i go back down to 2.77 vdimm and 20x fsb?

No IMO 2.9 is ok as long as your system is stable, and you have good airflow in your case you should be fine.

ive been at 2.9 vdimm for almost 3 months...no problems at 220 fsb

im using corsair xms pc3200LL with the platinum heat spreaders

if you have good heatspreaders and EXCELLENT air flow then i don't think you have to worry... OCZ el gold edtion ram sticks have extended their warrenty to 2.9vdimm.. becaues of their gold plated ram heatspreaders. and we all know gold is a pretty damn good conductive material... i say.. 2.8vdimm to play it on the safe side, if you have normal heatspreaders. and you can use 2.9vdimm if you won't keep your ram for longer then a year, or you have good cooling on your ram sticks

Just a nit-picky detail but I think OCZ could have saved some money and even gotten better overall thermal conductivity with silver plated heatspreaders.

I guess the gold is just there for the "bling bling" or the aesthetic appeal.

isn't gold more conductive then silver?

i always thought that gold was a heat reflector... they used it on space shuttles to reflect solar heat and also use it in car engine bays to reflect heat from getting to the cabin

As you can see, Au has thermal conductivity that is worse than Cu and Ag but better than Al.

So if you're running RAM w/o a heatspreader 2.8 is the highest you'd recommend?? Right now I'm running vdimm @ 2.7V, case temp 31-33C, CPU 47C.
XP2100 @ 2.2G (200x11)
Buffalo tech PC3700 is only at "Optimal" timings 8-4-4-2.5

Gold is used in spacecraft applications to reflect heat. Usually, a Multilayer Insualtion (MLI) blanket is made to protect parts exposed to the Sun.

Several inner layers of silverized Mylar and an outer layer of Gold Kapton are used to:
1. Outer Gold layer reflects the heat from the Sun.
2. Inner Silver layers are wrinkley so there are very few points touching between layers. Viola no heat conduction. Inside stays cool.

Maybe OCZ is using Gold to reflect the heat from other components.

my motherboard only lets me set 2.8v as my highest voltage

**sapasion** · 08-03-2003, 02:28 PM

I ran over 3v thru some old crucial pc2100 for several months without issues. Quality ram can take extra voltage

**mystifmagic** · 08-03-2003, 03:07 PM

My old Samsung PC2700 ran 3.0vdimm at 185Mhz FSB on a KT333 wonderfully and my consair PC3200 plat runs it well too. As long as you have good ram (which you do) and good cooling you should be fine.
