I built my pc (with some great help from people on this form TYVM! ) about a year and a half ago. The specs are/were:
Processor: Q9300 oc'd to 3.2Ghz (7.5x427)
Ram: Corsair XMS2 DDR2-6400 4x1gb
GPU: ATI 4870 2gb oc'd (probably not relevant for this question )
However, settings in the Bios show that it isnt running anywhere near 1600mhz like the website says it should. I get a setting of 1066mhz (I think, I need to couble check that and I will edit if its different).
I can change the settings to reach 1600 only when I dont oc the processor. However,I dont want to do that.
Current stable settings are:
DRAM Volt: 1.5V
DRAM Termination and Ch A + B Reference: 0.75 (all of them)
Performance Enhancement: Standard
(G)MCH Frequency Latch: 400MHz
System Memory Multiplier: 2.00D
I was able to set the DRAM Timing to the settings from the specifications. 9-9-9-27.
I tried a number of settings but I dont pass the post tests when I do and then the bios complains about potential over volting when I return to the configuration screen.
Well, that's about all the information I can think of at this second. If you need anything else, I can find it out.
Sorry for double post, but I cannot edit the above post.
Just some additional info about the System Memory Multiplier:
2.00D - Gives 854MHz and is stable but only as fast as the DDR2 Ram i upgraded
2.66D - Gives 1139MHz
3.33D - Gives 1423MHz - And seems stable now that I tried again... But not quite 1600...
4.00D - Gives 1708MHz and will not pass POST tests.
I tried a number of other settings but most dont pass the post tests and then the bios complains about potential over volting when I return to the configuration screen eventhough they are in safe levels...
Is 1423MHZ the best I will be able to do? I mean I read on there about people OCing to 2000MHz, but I am not interested in OCing the Ram, just interested in getting it to normal settings.
