capybara Posted October 14, 2007 Share Posted October 14, 2007 im seeing alot of 2.2v ddr2, usually rated pc6400. is this usable on a mother board with no option to adjust the Vdimm past the stock 1.8 volts ? sometimes, always, never?

XeroGlitch Posted October 15, 2007 Share Posted October 15, 2007 My OCZ DDR2 6400 mem is running @ 3.0v In fact before i bought it i did a little research and was told that this mem cant be run any lesser on my Gigabyte GA-M55SLI-S4. Wich was completely true. It shows up red in Bios with this setting, but it's normal. I've been running it this way for a year now.

Azurael Posted October 15, 2007 Share Posted October 15, 2007 I hope you mean 2.0v, because 3.0v would fairly rapidly fry most DDR2. My GeIL PC6400C4 is specced for 1.8-2.3v. It runs it's stock speed and timings (400MHz, 4-4-4-12) fine at 1.8v. It needs 1.9v to do 450MHz and pass more than a couple of MemTest86+ runs, which is 1:1 sync with my FSB at the moment. Not too bad Link to comment https://www.insanelymac.com/forum/topic/66406-18v-or-22v-for-ddr2/#findComment-471441 Share on other sites More sharing options...
Loyx Posted November 1, 2007 Share Posted November 1, 2007 2x1Gb OCZ Platinum DDR2 PC6400 @ 2.1V (4-4-4-12) 1:1 with E6600@3,2Ghz here... working fine Link to comment https://www.insanelymac.com/forum/topic/66406-18v-or-22v-for-ddr2/#findComment-490789 Share on other sites More sharing options...
methodinsane Posted November 5, 2007 Share Posted November 5, 2007 First Post:Like Loyx I have the OCZ Platinum Rev 2 PC2-6400. It's spec'ed for 1.8v to 2.1v though they offer a warranty for up to 2.2v. I'm new to overclocking but I've overclocked my E6420 from 2.13GHz to 3GHz at stockvoltage (1.35v) on a QuadGT board. I've set the ram to 2.1v (which I've read it really should be set at especially if doing basic overclocking) and running 4-4-4-15 (spec'd timings.) @ 1:1 ram/fsb. I'm defo gonna push timings down and and see how far I can go. I want to push the cpu higher, temps are fine using Arctic Freezer 7 Pro @ 3GHz (27c at normal room temp, 50c on load with Orthos.) I know I can go higher but I'm still a novice and want to learn more and play around with it a bit more. Still good ram from the looks of it and gets good reviews and the warranty aids you when the need to up the voltages arrive. My OCZ DDR2 6400 mem is running @ 3.0vJesus, can RAM run at 3.0v? what cooling do you have on there?

Loyx Posted November 5, 2007 Share Posted November 5, 2007 My OCZ DDR2 6400 mem is running @ 3.0v Obviously is a typographical error... xD Link to comment https://www.insanelymac.com/forum/topic/66406-18v-or-22v-for-ddr2/#findComment-495942 Share on other sites More sharing options...
