Rais Posted January 13, 2006 Share Posted January 13, 2006 Hi there. Because it said "2-3-3-6 on Intel and AMD based systems" i expected it to do so as well. Unfortunately it didn't on my Asus K8N-e deluxe MB. My bios gave the memory 2,5v so i upped it to the recommended voltage. This didn't help. The system, or should i say Windows, didnt boot at the prescribed timings, and i would have to clear CMOS, something i have now learned thx to this kit.:sunglasse Now i have another MB, the DFI Lanparty UT nF3. I hoped it would work at CAS2 on this one but it didnt. I have the same problem. Can you tell me what i have to do to make it work at the timings for which i buyed this kit?

Corsair Employees RAM GUY Posted January 17, 2006 Corsair Employees Share Posted January 17, 2006 For AMD the speed settings are 2.5-3-3-6. Link to comment Share on other sites More sharing options...
Rais Posted January 19, 2006 Author Share Posted January 19, 2006 Ok, thx for your reply. But i still dont understand why it say's "2-3-3-6 on intel AND! amd systems in the product sheet. I think you should change the product sheet because it is giving me information that isn't correct. You should change it back to 2,5 for AMD. I know it used to be cas2 for intel and cas2,5 for amd. But since this info was changed people i asked told me it was cas2 for amd as well. I bought this memory because it was said to be able to run at CAS2 in my system. But now it doesn't i can't really say i'm happy. What is your thought about this? Link to comment Share on other sites More sharing options...
Wired Posted January 20, 2006 Share Posted January 20, 2006 Last time I checked, it was like this: Intel: 2.0-3-3-6 AMD Athlon64: 2.0-3-3-6 AMD AthlonXP: 2.5-3-3-6 Link to comment Share on other sites More sharing options...
Rais Posted January 21, 2006 Author Share Posted January 21, 2006 Excactly, and since my CPU is an Athlon the memory ought to be able to run at CAS2. As i said in the startpost it doesn't on 2 motherbords i have had. So my question remains the same. Have you got an idea why? thx Link to comment Share on other sites More sharing options...
RJLeong65 Posted January 21, 2006 Share Posted January 21, 2006 Last time I checked, it was like this: Intel: 2.0-3-3-6 AMD Athlon64: 2.0-3-3-6 AMD AthlonXP: 2.5-3-3-6 Not quite. The 2.0-3-3-6 timings apply only to the Intel platforms, and the AMD Athlon 64 platforms with Rev. E (Venice/San Diego/Manchester/Toledo/Venus) processors. Socket A AMD Athlon XP platforms and most (though not all) of the AMD Athlon 64 platforms with Rev. C (Newcastle/Clawhammer) or D (Winchester) processors require the 3200C2 modules to run at CAS 2.5 instead of CAS 2. Rais, You have an early revision (Rev. CG) Athlon 64 3700+ processor - and a Socket 754 model, at that. The early Athlon 64 memory controllers found in the Rev. C and Rev. D CPU's have trouble running the 3200C2 modules at such tight latencies. Link to comment Share on other sites More sharing options...

Rais Posted January 26, 2006 Author Share Posted January 26, 2006 Dear people at Corsair, Its been 2 weeks and i still havent got even a tip. Plz help me? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 2, 2006 Corsair Employees Share Posted February 2, 2006 First thing you are posting in the worng ssection. Please set the Dim Voltage to 2.7X volts and then set the timings manually to the tested settings for the specific module you have, and then test the module/modules one at a time with www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. .

Rais Posted February 2, 2006 Author Share Posted February 2, 2006 Sorry didn't know where to post. I will try to run them seperately at CAS2. My problem is not that memtest is giving me errors. At CAS2,5 i've had several passes of memtest. The memory performs well at CAS2,5. However it will not run at CAS2 at all. I have already set the timings manually and i set the voltage to 2.8v. The problem is that my system does not boot at CAS2. Testing the memory in another system is possible, but i dont know anyone else with an AMD system. I'm happy that you are offering the service of replacement, but i was hoping for an answer that could solve this with this memory. Other people i spoke to on forums ran this memory at CAS2 on AMD systems with no problems and they also didn't know why it would not run here. I will try to run single module tomorrow and will post results. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 4, 2006 Corsair Employees Share Posted February 4, 2006 Again, did you test the modules one at a time to make sure one is not failing? And if they both pass what slots did you have them in with both installed? Link to comment Share on other sites More sharing options...
Rais Posted February 13, 2006 Author Share Posted February 13, 2006 Hi, sorry for the late reply, ive been busy. Today i tested the modules 1 by 1. I tried both single modules in all 3 slots. It will not work at CAS2. I got as far as booting but after a couple of seconds i get a blue Windows screen, and then my system boots automatically. It goes so fast that i can not read what is says, but i see numbers. In some cases it will not get that far, and the sytem boots again. I will then get to a black Windows screen with gray letters which tells me Windows could not boot. The passes that i've had were at CAS 2,5. I use slot 1 and 2. I've also tried CAS2 with both modules in slot 2 and 3 but that does not work. So i can conclude that it will not run at CAS2 with my knowledge. I do not know other things to try. Like i said i've had this problem with 2 motherboards. I understand that there could be many reasons why it will not work, besides the modules, but i dont know what it could be. What do you think?

leeghoofd Posted February 13, 2006 Share Posted February 13, 2006 Only thing you can do is try a different bios mate, also DFI ( mainly Nforce4) seems to have problems with Corsair ram. I would suggest you to visit n DFI forum ( I pm'd you a link) since there are many beta biosses for each memroy type used. And just to say I couldn't run CAS 2 either with my P4C800-E DLX but after some bios updates it fixed it. You mainboard is mature now ( no more childdiseases) and the latest bios should support the current ram types used. Try flashing it and see what gives Good luck mate. Also on a note there ain't much difference between Cas 2 and 2.5 Most performance is gained from 1T command rate and dual channel operation ( sadly the Socket 754 doesn't support the latter ) Link to comment Share on other sites More sharing options...
Rais Posted February 14, 2006 Author Share Posted February 14, 2006 I only will update my bios if it will be certain that that will solve my problem. Otherwise i may encounter new problems and my system is fine now. Link to comment Share on other sites More sharing options...
leeghoofd Posted February 14, 2006 Share Posted February 14, 2006 That might be a good idea and I seriously doubt if a bios update will solve those problems unless stated in the update file. My XL ram has never run with my 875 Intel chipset at Cas 2 , CAS 2.5 was way better regarding stability 24/7. Same with the Asus A8V and Abit Fatil1ty board.( runs fine now after 5 bios updates lol) It might just be some weird incompatability and also it ain't much, the performance difference between 2 and 2.5 CAS.

Rais Posted February 27, 2006 Author Share Posted February 27, 2006 Hi guy(s), I tried the kit on my new motherboard&cpu (see profile). Unfortunately i have the same problem on this hardware, it works fine at CAS2,5 but not at CAS2. This has finally convinced me that is is the kit. The first reason why i openened this thread/question was to find an answer to solve this. When the tips didn't work you offered me RMA, which i appreciate. But i hadn't immediately asked for an RMA at the shop where i bought this memory, because i wanted to see if i could solve it with my current kit. Now that i'm convinced it is the kit, i did ask RMA at the shop where i bought the memory. I did this last night and they have already agreed and i can send it back to them. I will choose this options because they are near me and i can get a new kit within 5 days if i send it them today. I'd like to thank Corsairs people and all others for the help and service. I will let you know when i get my new kit and tell y'all it's working :D: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 27, 2006 Corsair Employees Share Posted February 27, 2006 I would check that the PSU you have meets the requirements for the Video card you have, I think it needs about 26 amps and your PS may on have about 14 amps that might cause this error.
