jcrawfor74 Posted December 16, 2012 Share Posted December 16, 2012 Hi, I probably should have found this page before I purchased my RAM, but.. I have a HP Pavilion dv6 - 3030tx. It can accept up to 8GB ram (2x4GB). What RAM would you recommend for this system. The machine is a Core i5, and runs its current memory at 533Mhz and 7-7-7-20. I hope you say the CMSO8GX3M2A1333C9, (which I just purchased)? Cheers Link to comment Share on other sites More sharing options...
peanutz94 Posted December 16, 2012 Share Posted December 16, 2012 Those should ru just fine. Although if your machine is currently running at 533mhz(1066mhz) the memory will downclock to match what your machine is running at now. So even though they are 1333mhz sticks they will only run at 1066mhz. Link to comment Share on other sites More sharing options...
jcrawfor74 Posted December 17, 2012 Author Share Posted December 17, 2012 Thanks Peanutz94. I would have thought so to, but with the Memory installed, Windows won't boot, (I have tried all the various safemode and startup options). I have run memory tests from the bios and these pass, but I tried to run MemTest 4.20 and it crashes after about 3 seconds. I managed to take a photo of the screen before it crashed and it is saying its running @ 7-7-7-20. So I am trying to determine if its faulty RAM or just the wrong type, before RMA'ing the memory. I will try MemTest on each module individually tonight and see if its just one or both. Link to comment Share on other sites More sharing options...
peanutz94 Posted December 17, 2012 Share Posted December 17, 2012 Have you tried clearing the BIOS yet? That should be done before switching memory and also be sure you have any firmware or BIOS updataes that would apply to your computer. Since the BIOS is still showing 7-7-7-20 i would bet the old settings are still stuck in the BIOS and need to be cleared before the new set will post.

jcrawfor74 Posted December 17, 2012 Author Share Posted December 17, 2012 Hi, Laptop is running the latest bios, and I have now reset the bios prior to running the following memtest's. I have now tested both memory modules individually and in each available memory slot, (only 2 on this laptop). In all cases MemTest 4.20 (and 4.15) crash after a few seconds of running. I think you will find that the core i5-540m will only run @ 1066Mhz, the following is from the dv6 manual.. "..(only computer models equipped with the Intel Core i7-840QM 1.86 GHz processor, the Intel Core i7-820QM 1.73GHz processor, the Intel Core i7-740QM 1.73 GHz processor, and the Intel Core i7-720QM 1.6 GHz processor run at DDR3/1333-MHz; all other computer models run at DDR3/1066-MHz)" Again thanks for your help. I am hoping RAM guy can confirm or deny compatibility with this memory. Thanks Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted December 17, 2012 Corsair Employee Share Posted December 17, 2012 I am sorry but we do not have this system listed on our memory configuration tool so I am sorry I cannot confirm it will work with these modules. I would suggest speaking with HP for more information on your system. Link to comment Share on other sites More sharing options...
jcrawfor74 Posted December 19, 2012 Author Share Posted December 19, 2012 Hi Ram Guy, What other information do you require? The laptop is a HP core i5-540M. (http://ark.intel.com/products/43544/Intel-Core-i5-540M-Processor-3M-Cache-2_53-GHz) It has a maximum supported memory of 8GB The maximum supported memory speed is 1066Mhz. The memory currently installed is as per screen shot. I thought that the 1333Mhz memory would downclock to 1066Mhz and run at the required 7-7-7-20 CAS latencies, or is this assumption wrong? (Note: I have a corresponding forum post going on over on the HP support site.. no luck so far.. http://h30434.www3.hp.com/t5/Hardware-Upgrades-Replacements/Memory-Compatibility-for-HP-Pavilion-dv6-3030tx-WX050PA/td-p/2258923) Thanks Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted December 20, 2012 Corsair Employee Share Posted December 20, 2012 The issue is the specific Chipset that the NB is using, if its H55 then our modules may not be supported as they can be made with 512m X 8 memory IC's which that chipset would not support. Only modules made with 256M X 8 would be supported on these older chipsets. That would be what you would need to find out from HP, if they even know? However you can try them if you like but I would check on the resellers return policy if the will not work there is not a lot we can do. Link to comment Share on other sites More sharing options...
jcrawfor74 Posted December 21, 2012 Author Share Posted December 21, 2012 Hi RAMGuy With knowledge comes power! Ok, the Pavilion dv6 3030tx runs an Intel HM55 southbridge chipset, so this would explain the memory incompatability. I have managed to track down some 2x4GB memory with 256Mx8 IC's and I will update this post once they have arrived and I have tested them. Link to comment Share on other sites More sharing options...
jcrawfor74 Posted March 3, 2013 Author Share Posted March 3, 2013 Sorry for the late update. The RAM was a competitors brand so will not name names here, but it was spec'd as DDR3-1066 4G/256x8. The issue was correctly identified as the requirement for the memory to be 256M x 8. I have been running successfully with this memory for 3 months now with no issues. Thanks Ram Guy Link to comment Share on other sites More sharing options...
mk83 Posted March 10, 2015 Share Posted March 10, 2015 Would CMSO8GX3M2A1333C9 work in HP Pavilion dv6 - 3138eo ? It can accept up to 8GB ram (2x4GB). The machine is a AMD Phenom II N930 processor, and runs its current memory at 1333 MHz. Link to comment Share on other sites More sharing options...
Corsair Employee Greybeard Posted March 10, 2015 Corsair Employee Share Posted March 10, 2015 Try our memory configurator, http://www.corsair.com/en-us/memory-finder and see if that set is compatible or not with your system. Link to comment Share on other sites More sharing options...
