KloudSwift Posted January 30, 2008 Share Posted January 30, 2008 Hello. I purchased a CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory... TWIN2X2048-6400C4DHX for my Compaq Presario SR5023WM which uses an Asus motherboard model called IVY (Asus' website has no info on this board). Here is a link for Compaq/HP of the board... http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c01237548&cc=de&lc=en&dlc=en&dlc=en&lang=en. I love the dimms, there are great but I can't seem to get its memory timimg to its tested settings of... DDR Clock: 800 SDRAM CAS Latency: 4T SDRAM RAS to CAS Delay (tRCD): 4T SDRAM Row Precharge (tRP): 4T SDRAM Active to Precharge Delay (tRAS): 12T DRAM Voltage: 2.1v TRC: 24 When I run CPU-Z it reads as: SDRAM CAS Latency: 5T SDRAM RAS to CAS Delay (tRCD): 5T SDRAM Row Precharge (tRP): 5T SDRAM Active to Precharge Delay (tRAS): 18T TRC: 23 Don't what the voltage is set to. When I enter the bios there is no settings for changing Ram Timimgs. I read elsewhere about how Compaq computers hide these settings in the bios. I talked to there helpdesk and they said the same. They did told me to try a key combination with the F10 key to enter the bios and all it did was give a couple of more options on the bios but not what I was looking for. I have the latest Bios from Compaq support and don't if I want to flash my bios or even try any other modification program to enable, unlock or add other menus the bios. I don't know what to do. Has anyone had any success in changing the timimgs on a compaq or other OEM PC or even know of a way to get around this. Anything would help. Please Advice. Thanks.

KloudSwift Posted January 31, 2008 Author Share Posted January 31, 2008 Please look up your system on our memory configurator and use only the memory that was listed for your system. I looked and my system is not listed. I have a Compaq Presario SR5023WM and all you have listed is a Compaq Presario SR5023HK. Link to comment Share on other sites More sharing options...
RJLeong65 Posted January 31, 2008 Share Posted January 31, 2008 I looked and my system is not listed. I have a Compaq Presario SR5023WM and all you have listed is a Compaq Presario SR5023HK. Both of those models are of two different platforms: Your SR5023WM is an AMD platform using DDR2 memory, while the SR5023HK is an Intel-based platform also using DDR2 memory. And since your particular system is not listed in the Corsair system configurator, you might have to contact HP/Compaq for a list of memory modules (complete with brand and model names) recommended by the company. And no OEM system has any provision at all whatsoever to manually adjust the DIMM voltage. In the case of your system, the DIMM voltage is "permanently" locked at the JEDEC-reference value of 1.8V. All of Corsair's 6400C4 series modules, by contrast, require a DIMM voltage of 2.1V in order to run reliably at the tested speed and timings. And since there is no way to bring your system to run its memory slots anywhere near 2.1V, you have no choice but to buy conservative memory rated for 5-5-5-18 or 6-6-6-21 timings at DDR2-800 speed.
