sdlvx Posted November 1, 2005 Share Posted November 1, 2005 I recently purchased G. Skill DDR 550, and it didnt work well with my system. Before I go on, here are the system specs. Gigabyte 8IK 1100 Rev 1.0 A2 875p Chipset Intel Prescott 3.2 Ghz C0 Stepping ATI Radeon 9700 Pro Thermaltake Xaser Silent Purepower 540w Currently G. Skill DDR550 Extreme Edition Ram (2x512)(In the process of being returned) Previously 1.5Gb XXXX ValueRam PC3200 M-Audio AudioPhile 2496 Maxtor 7L300S0 300 GB SATA Hard drive Western Digital WD1200JB LiteOn DVD-Rom LTD163D Liteon LTR 52246S (CD Burner) Although the G. Skill is rated for DDR 550, I can not achieve this overclock. In fact, I can not overclock the ram more than 10 Mhz (DDR 410) without serious stability issues. Even changing the timings does not help. What I find perplexing is, is that i am able to run 5:4 system bus at 232 stable as a rock. I have read that Samsung chips should be avoided with intel chipsets, and G. Skill has samsung chips. I have done everything possible to get this G. Skill to overclock and it will not (overvolt, timings, BIOS update, repair windows, etc). Please also note the G. Skill was doing fine in memtest running at DDR422 until it reached test #7, where it fell on its face. I am looking at CORSAIR XMS 1GB (2 x 512MB) 184-Pin DDR SDRAM DDR 550 (PC 4400) Unbuffered Dual Channel Kit System Memory Model TWINX1024-4400C25PT, because I have heard it has Hynix chips instead of Samsung. Will this ram be able to run on this system? If not, what else would you recommend. I am eager to overclock my system and run 1:1, 5:4 and 3:2 just dont cut it. Also, I was reading reviews and comparing the DDR500 and DDR550 chips, and it appears more people with pentiums run with DDR500, and more AMD users with DDR550? Does DDR 500 run better with intel chipsets? Id always prefer more headroom for my OC and would prefer DDR550. Also please note I bought this motherboard when it was relatively new. I am not sure if intel revises their chipsets and its possible i just have an old chipset. I have no temp issues as well, as i have 7 case fans, a custom heatsink, and active ram cooling, not to mention, i have been over the whole thing with a temp probe. Also, when i overclock, I have the agp/pci/src bus locked at normal speeds to avoid instability, so I am sure that is not it.

Corsair Employees RAM GUY Posted November 1, 2005 Corsair Employees Share Posted November 1, 2005 That is more than likely the CPU, as the CPU you have when running 1-1 will top out at about 205-220 Mhz that is normal. Link to comment Share on other sites More sharing options...
sdlvx Posted November 1, 2005 Author Share Posted November 1, 2005 But how can i pull 232 stable when running 5:4? And all my crashes are blue screens, it doesnt freeze. IRQL_NOT_LESS_OR_EQUAL and errors in win32k.sys Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 1, 2005 Corsair Employees Share Posted November 1, 2005 I would suggest you do a bit more research on the web, but this is because of chipset loading. There is more loading on the CPU and chipset when running 1-1. In fact I would suspect you can get close to 240 Mhz with just one module installed.

sdlvx Posted November 1, 2005 Author Share Posted November 1, 2005 it did make a difference, is there anything i can do, or am i limited to buying a new motherboard? Better northbridge cooling maybe? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 1, 2005 Corsair Employees Share Posted November 1, 2005 No the only option would be to try another CPU, one that over clocks better. Sorry! Link to comment Share on other sites More sharing options...
