smax Posted August 22, 2007 Report Share Posted August 22, 2007 Apple says my computer has GDDR3 memory, but how would you tell what kind of video memory you have installed in a computer? I just did a quick search and didn't find anything... So how can you find out? Quote Link to comment Share on other sites More sharing options...
Guest Michael Posted August 22, 2007 Report Share Posted August 22, 2007 type dxdiag in the run thingy... there you can see if it's true what they say greets michael Quote Link to comment Share on other sites More sharing options...
smax Posted August 23, 2007 Author Report Share Posted August 23, 2007 (edited) Dxdiag won't have anything about video ram type. Let me check though, just to be sure... Yep, nothing. Edited August 23, 2007 by smax Quote Link to comment Share on other sites More sharing options...
®®® Posted August 24, 2007 Report Share Posted August 24, 2007 If there's one program that may include the distinction between GDDR2 and 3, it's Everest. Nothing else comes to mind. It was always a problem to get a defenitive answer for the used RAM type on graphic cards as long as you can't easily on the RAM chups and google for the printed numbers on the chips. Mostly it's samsung and they have a heap of datasheets available so then it's easy to find out. Quote Link to comment Share on other sites More sharing options...
RangerXML Posted August 24, 2007 Report Share Posted August 24, 2007 Normally Rivatuner would, but it doesn't seem to work to well with the newer cards (8x00) and drivers. Quote Link to comment Share on other sites More sharing options...
zipper Posted August 24, 2007 Report Share Posted August 24, 2007 Still worth a try. Quote Link to comment Share on other sites More sharing options...
RangerXML Posted August 24, 2007 Report Share Posted August 24, 2007 Its just RivaTuner tells me my 8600M GT has 512MB of DDR3, when its pretty much common knowledge that my card only has DDR2 on it. Quote Link to comment Share on other sites More sharing options...
smax Posted August 25, 2007 Author Report Share Posted August 25, 2007 Hmm... So Rivatuner does report it correctly. "128-bit G84 (A2,32sp) with 128MB DDR3" Quote Link to comment Share on other sites More sharing options...
Guest Csma Posted September 18, 2007 Report Share Posted September 18, 2007 The apple 8600M GT is one of the few manufacturers that uses DDR3 for their cards. I hear ASUS does too in their higher end laptops. So yours is DEFINITELY DDR3. Quote Link to comment Share on other sites More sharing options...
Guest Guest Posted September 19, 2007 Report Share Posted September 19, 2007 Riva reports my 8600m gt as ddr3 version too (dell vostro) Quote Link to comment Share on other sites More sharing options...
Morthal Posted September 19, 2007 Report Share Posted September 19, 2007 In Dell Vostro 1500 there is DDR2 version, RivaTuner is wrong. Check the clockspeed and you will se that memory is running on 400Mhz (DDR2, DDR3 has 700MHz). Quote Link to comment Share on other sites More sharing options...
strekship Posted September 20, 2007 Report Share Posted September 20, 2007 I seem to be having trouble getting a definitive answer from programs. RivaTuner tells me my 8600m GS is DDR3, while Everest says its DDR2. I am pretty sure it is DDR2 because of the clocks. Quote Link to comment Share on other sites More sharing options...
sheldo86 Posted September 27, 2007 Report Share Posted September 27, 2007 As a rough rule of thumb, the 8600 GT DDR2 version is getting aroud 3200-3300 in 3dmark06 and the DDR3 version around the high 3000's i think, like 3800. This is a rough guide only (I dont have both verison infront of me to compare exactly, so dont flame me :) )...I suggest using to 3dmark06 and if your getting low 3000s you've got the ddr2. In real world tests (i.e fps in games) I think you would notice little diff. Quote Link to comment Share on other sites More sharing options...
Guest Cain Posted October 7, 2007 Report Share Posted October 7, 2007 All the 8600M GT are the same and they have DDR3, the only problem is they came in three versions, the 128 MB DDR3 w/ TurboCache 128 MB (System Memory now a days is DDR2), the 256 MB DDR3 (I have heard of someone putting turbo cache on to support 512 MB), and the 512 MB DDR3. The 512 MB DDR3 is only found in 17" laptops or bigger. I believe its MXM Type 3 they are called. Now, if you have the 8600M GS - sorry but you only have 128 and 256 mb flavors and they are in DDR2.

smax Posted October 7, 2007 Author Report Share Posted October 7, 2007 The GT IS available in both DDR2 and GDDR3... it's up to the manufacturer to determine which to use. Quote Link to comment Share on other sites More sharing options...
