Hey all, quick question since im out of the loop with AMD at the moment. building an AMD 955 system using a Gigabyte GA-880GM-UD2H and it states RAM Voltage@ 1.5V but the RAM ive spec'd is 1.65V is this an issue ? im guessing its not as i cant even find any 1.5V 1600mhz kits but i just wanted to be sure as ive seen 1.8V stuff that is for AMD as well ????
The Corsair Vengance RAM is 1.5v. 1.65v will be fine, it will not be an issue but the industry is moving to 1.5v via the new DRAM IC's (ala Sandy Bridge where 1.65v is the absolute maximum). If you buy 1.5v, you will be more future proof I reckon. If short on money, get the 4GB Corsair kit (e.g. CMX4GX3M2A1600C9 - 4GB (2x2GB) Corsair XMS3 DDR3 PC3-12800 (1600), Non-ECC Unbuffered, CAS 9-9-9-24, XMP, 1.65V), it will work fine with an AMD rig (I built one in November with that and a 955 BE). If you can afford it, the 1.5v Vengance 4GB kit is £50 (CMZ4GX3M1A1600C9 - 4GB Corsair Vengeance DDR3 PC3-12800 (1600), Non-ECC Unbuffered, CAS 9-9-9-24, XMP, 1.50V). I asked Bindi about this earlier in the context of the Sandy Bridge RAM article... http://forums.bit-tech.net/showpost.php?p=2540878&postcount=40 His response... http://forums.bit-tech.net/showpost.php?p=2541370&postcount=41
awesome thanks fingers i was rpetty sure but not 100% i dont think getting 1.5V RAM is worth it for waht i need as im building 3 machine all identical and the 1.5 stuff is £10 more per PC anyone think ill save enough on electricity by dropping 0.15V per machine ?
If it was me I would only buy the 1.5v if I was going to re-use the RAM in a Sandy Bridge rig in the future.
lol not likely these are office type PCs that will be here until they break its the reason i opted for a quadcore and 4GB of RAM instead of a dual core and 2GB of RAM which is fine for now but not in 2 or 3 years
You will save, but only a little. I seem to remember kingston or someone release 'green' RAM that only needed 1.35 or something. Savings wasn't a lot, but if the price difference isn't a lot, and you don't need to overclock massively, might aswell save what little you can
