Angeline Posted August 18, 2007 Share Posted August 18, 2007 First off! System specs... Compaq SR1750NX AMD 2.2GHz Athlon 64 3500+ Venice 2 sets of Corsair VS1GBKIT400 (4x512MB) 512MB ATI Radeon X1300 200gig HD (SATA) DVD-RW drive Onboard realtek sound HIPRO PSU (max output 300w) Computer runs well (no freezing at all) with: 1.) The Nanya memory that came with it, heh 2.) 1 set of the Corsair VS1GBKIT400 (2x512MB) by itself 3.) The factory Nanya memory that came with the Compaq (2x512MB) together with VS1GBKIT400. Mixing memory doesn't seem to bother it. However, it is hard freeze city running all 4 sticks of Corsair. It happens randomly. Computer boots just fine, and sometimes I can go an hour without anything going wrong...and then it just FREEZES! No mouse response, can't ctrl-alt-delete out of it or anything. Everything has been Memtested, different configurations, several passes...no errors. I'm thinking I don't have enough PSU to run the memory, but I can run 2 gigs of mixed ram, so I don't know. The timings are correct and I'm running at 2T. Seing as it is a Compaq, the BIOS is locked and I can't even see what voltage the ram is running at, nor can I change anything. Please help! Thanks in advance. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 20, 2007 Corsair Employees Share Posted August 20, 2007 I am sorry but you should not MIX memory with most systems especially OEM systems that will not let you make any changes in the BIOS setup, if our modules will run and pass http://www.memtest.org with our problems when installed alone then I am sorry there is not much that can be done.

Angeline Posted August 20, 2007 Author Share Posted August 20, 2007 I understand that, but why does it freeze with 2 sets of VS1GBKIT400(4x512MB)? They're matched sets! That's the big question. Thanks for the response. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 20, 2007 Corsair Employees Share Posted August 20, 2007 Does each set run with out problems? If so that might suggest a power issue I would suggest trying a Bigger PSU and check with the system builder and see if they have a newer Bios. It takes about 12 watts per module and the PSU you have listed will start to top out at about 220 Watts continuous out put. Link to comment Share on other sites More sharing options...
Angeline Posted August 20, 2007 Author Share Posted August 20, 2007 Yeah, each set runs fine by themselves. So that ends that...need to get a board that isn't locked up and more powerful PSU. I guess one other quick question before I go. The first set of the VS1GBKIT400 I bought in August of 2006 are doubled sided (16 chip) and the ones I bought a few months ago of the same set are single sided (8 chip) That really doesn't make any difference does it?

Corsair Employees RAM GUY Posted August 21, 2007 Corsair Employees Share Posted August 21, 2007 It should not, but some MB's are picky when mixing memory, we can try and RMA all of them if you like. Link to comment Share on other sites More sharing options...
