Fisherman Posted February 25, 2005 Share Posted February 25, 2005 I built a PC a couple of years ago based on a Giga-byte 8PE677 Ultra 2, it has 1 x 512Mb of CMX512-2700C2PT, 2x WD 80Gb Hard Drives (JB Type), XP (Sp2), a Matrox RT.X10 card and amongst the normal home use stuff it is used to edit video using Adobe Premiere 6.5 + Photoshop. I plan to build a higher spec PC next year, but in the meantime want to boost the performance of this one. Is it better to add another 512 Mb of exactly the same type ( I may have problems matching the version) or go for a matched pair and if so why? Is it better to go for 1 x 1Gb ? The board only supports speeds up to 333 so faster memory will not be utilised to it's best, (unless it's cheaper to go that route ?) How does the latency affect the overall speed (ie does the amount of memory counteract the drop off in latency) and is it beneficial to go for memory speed rather than latency ? I believe Premiere is memory intensive when compiling and I want to try and boost the machines performance. The other thing is at this stage I don't want to spend an excessive amount, so if I could retain my existing 512Mb so much the better. On a non memory issue do you know if adding an additional hard drive for the base software and combining the two WD 80Gb drives in a RAID 0 layout (just for the video ) boost performance ?

Corsair Employees RAM GUY Posted February 25, 2005 Corsair Employees Share Posted February 25, 2005 Roger, My suggestion would be to wait till you upgrade your system and get new memory to match the MB you get. However, to answer your questions, if you want to add to what you have now, you would indeed need to match the modules part# and revision you have now for best performance. Or replace the module with one VS1GB333 modules for best value. Is it better to go for 1 x 1Gb ? A: With this MB yes! The board only supports speeds up to 333 so faster memory will not be utilized to it's best, (unless it's cheaper to go that route?) A: Yes I would agree with this statement! How does the latency affect the overall speed (ie does the amount of memory counteract the drop off in latency) and is it beneficial to go for memory speed rather than latency? A: This is a hard question to answer because the make and model of MB and the chipset used can have or make a difference. But a soft rule of thumb to follow would be something like: With Cass 3 as a base line then Cass 2.5 would be about 1-3 % faster and Cass 2.0 About 1-3% faster again. The other thing is at this stage I don't want to spend an excessive amount, so if I could retain my existing 512Mb so much the better. A: Again, if you add to what you have now you should match the same part# and revision for best performance. On a non memory issue do you know if adding an additional hard drive for the base software and combining the two WD 80Gb drives in a RAID 0 layout (just for the video ) boost performance ? A: Yes running 2 HDD's in a raid configuration will enhance the HDD performance. IE: One HDD at 133 Mbs verses 2 at 133 Mbs would translate to 266Mbs of theoretical bandwidth. However, in real practice you do see an improvement but I have yet to see the full bandwidth. You might do a search for HDD's or Raid controllers and you will probably find some comparisons to give you a better idea. Link to comment Share on other sites More sharing options...
