dsheppard Posted May 4, 2009 Share Posted May 4, 2009 I have an ASUS M3A32-MVP DeLuxe m/b, an AMD Phenom 9950, currently with 4Gb (2 x 2Gb) of Corsair DDR2 1066 (which works at the default of 800Hz, ho hum). I wanted to add another 4Gb of the same memory. It won't boot; the POST doesn't even start. Everywhere on the web I read "Set this timing in the BIOS, set that Voltage, 5, 5, 15 doo-dads ..." ... HOW? It has an AMI BIOS; there are no options in the BIOS to set any of this stuff! I have the AMD Overdrive software which, in theory, allows me to view/set all these esoteric settings, but none of the posts on the web refer to use of this software, and none of the TLAs mentioned in the posts match the TLAs in this software. What do I do to get this working? What is everyone who is making these posts ACTUALLY doing? Could someone (hint: ASUS, Corsair ... after all, these are your products) please produce a clear, simple guide to getting this working. Why is it so difficult? You should just plug in the RAM and it should JUST WORK! Shouldn't it? :): I would be extremely grateful if somebody could help me with, or point me to, a start-at-the-beginning, step-by-step guide to getting 8GB of Corsair DDR2 1066 RAM working on an ASUS M3A32-MVP DeLuxe m/b with an AMD Phenom 9950.

DerekT Posted May 4, 2009 Share Posted May 4, 2009 Your AMD memory controller does not support four slots at 1066Mhz. It supports one channel at 1066Mhz and often can't even run at that speed. With four modules you may have to drop to 800 or even 667MHz. Download Memtest86+ V2.11 from--->Hereand extract the ISO image. Burn the ISO image to an CD-ROM disk. Download CPU-z from Here . Shut the system down. Insert a single stick of memory in the first slot (Closest to the CPU). Restart, press the delete key and enter your BIOS. If you can not find your BIOS or do not know how, then you need to find someone who does. Load setup defaults, save setup defaults and set to these values: Jumperfree Configuration AI Overclocking: Manual FSB Frequency = 200 PCI-E Frequency = 100 Processor Frequency Multiplier = x13.0 2600Mhz Processor Voltage = Auto Processor NB-Voltage = 1.325v CPU VDDA Voltage = 2.6v CPU-NB HT Link = 2.0Ghz DDR Voltage = 2.1v NorthBridge Voltage = Manual HyperTransport Voltage = 1.30v Core/PCI-e Voltage = 1.2v NB PCIe PLL = 1.9v SouthBridge Voltage = 1.25v Auto Xpress = Disabled CPU Tweak = Enabled Memory Configuration Bank Interleaving = Auto Channel Interleaving = Auto MemClk Tristate C3/ATLVID = Disabled Memory Hole Remapping = Enabled Unganged Mode Support = Disabled Power Down Enabled = Disabled Read Delay = Auto DCQ Bypass Maximum = Auto Dram Timings Configuration Memory Clock Mode = Manual Memclock Value = 800 Mhz 2T Mode = Enabled DRAM Timing Mode = Both CAS Latency (CL) = 5 CLK TCWL = Auto TRCD: 5 CLK TRP: 5 CLK TRAS: 15 CLK TRC: 22 CLK All other Set to AutoShut the system down. Insert a single stick of memory in the first slot closes to the CPU. Restart and boot to the Memtest CD allowing for two full passes. Shut the system down. Remove the first stick and insert the second stick in the third slot. Retest. Finally, insert a stick in the first and third slots. Retest. Results?

dsheppard Posted May 7, 2009 Author Share Posted May 7, 2009 Derek, Many thanks for your prompt reply, which got me started in the right direction. However, it still refuses to boot with 8GB, although it has done occasionally - very frustrating. So, I went into the BIOS configuration and found 'Jumperfree Configuration' under the 'Advanced' tab and set everything as you described, with the following exceptions/observations/questions: The SouthBridge Voltage could not be set to 1.25V, it always automatically changed to 1.26V. I couldn't see an 'Unganged Mode Support' option, only a 'Ganged Mode', although Unganged was shown in the right-hand pane. I set the Memclock Value to 800 - this worked fine with 2GB and once with 8GB. I then set this value to 1067 (which is what I expect to be able to set it to - although why 1067 and not 1066?) and again it worked fine with 2GB and once with 8GB. If, with 8GB installed, I set DDR Voltage to 2.1V it would never boot. I set it to 2.2V on the basis of some other articles about this problem and it booted ... once. Another field, 'Processor-NB Frequency Multiplier', which defaults to 'Auto' is not mentioned in your description ... I know you say 'All other set to Auto' but is this one included in that or should I set a specific value? Regards, David Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted May 8, 2009 Corsair Employee Share Posted May 8, 2009 I would not mess with the SB Voltage and with 4 modules DDR667 or DDR800 would be suggested. and set the NB/SPP/MCH Voltage to +.2 Volts over defalt. Link to comment Share on other sites More sharing options...
