Holger67 Posted November 16, 2007 Share Posted November 16, 2007 Hy Ram RAM Guy, I have build my first PC (2 x Dominator 2GB (2x1GB DDR2 (PC2-8500 C5 - 1066 MHz) and ASUS Striker Extreme Motherboard with intel Core2 Extreme). Now I have the problem, that I cannot install any OS - Blue screen always appears :confused:. I guess the problem is to find in the wrong BIOS settings (Phoenix VER: 1305). Can you tell me, WHERE and WHAT changes I have to make in BIOS, that the motherboard and the CORSAIR PC2-8500 C5 RAM will work together. At the moment, my BIOS is using the AUTO settings. I read in the internet, that AUTO settings should be the problem. The BIOS settings must be set manually. I hope, I will hear from you soon. Many thanks in advance for helping me! Best Regards from Germany Holger Link to comment Share on other sites More sharing options...
Yellowbeard Posted November 16, 2007 Share Posted November 16, 2007 Please set the memory voltage to 2.2v for rev 1.* memory or 2.1v if you have rev 2.* memory. Also, you may need to increase the SPP and FSB termination voltages to be stable with 4 modules due to the increased load on the memory controller. 1.4v each shoudl be good if you are unstable at auto settings and after raising the RAM voltage.

Holger67 Posted November 16, 2007 Author Share Posted November 16, 2007 Thanks for your fast answer. But I have one big problem - I have no idea where to change these settings? :confused: Are there also other recomendet BIOS-settings for my memory and Motherboard? :roll: where do I change these settings. :confused: Best regards Holger Link to comment Share on other sites More sharing options...
Yellowbeard Posted November 16, 2007 Share Posted November 16, 2007 They will be under the advanced settings in the bios. Please check the bios section of your manual. Link to comment Share on other sites More sharing options...
Holger67 Posted November 16, 2007 Author Share Posted November 16, 2007 Hi specmike, sorry to ask again. I need a little deeper help. I think, I have to change these settings in the "Extreme Tweaker" Phoenix-AwardBIOS section. But there are so many possibilities to change settings - this is very confusing to me. The BIOS-Manual is not much help for me either. Is it possible to give me some more precisely hints, where I have to change settings? Like this - (it is only an EXAMPLE!!!! - I found it here in the forum) Quote: Multiplier = 10 FSB = 266 DRAM = Unlinked and set to 800Mhz Memory Timing FSB - Memory Clock Mode: Unlinked CPU FSB: 266 CPU Multi: 10 DDR FSB: 800 tCL: 4 tRCD: 4 tRP: 4 tRAS: 12 Advanced Memory Settings tRRD: 5 tRC: 24 tWR: 6 tWTR: 8 tREF: AUTO tRD: 7 tRFC: 42 Async Latency: AUTO CMD: 2T CPU Spread Spectrum: Disabled PCIE Spread Spectrum: Disabled MCP PCIE Spread Spectrum: Disabled SATA Spread Spectrum: Disabled LDT Spread Spectrum: Disabled CPU Internal Thermal Control: Enabled Limit CPUID MaxVal: Enabled Enhanced C1 (C1E): Enabled Execute Disable Bit: Enabled Virtualization Technology: Enabled Enhanced Intel Speedstep Tech: Enabled LDT Frequency: 5x PCIEX16_1 Frequency (Mhz): 101 PCIEX16_2 Frequency (Mhz): 101 PCIEX16_3 Frequency (Mhz): 101 SPP<->MCP Ref Clock, Mhz: Auto Voltages Vcore = Auto Vdimm (DRAM Voltage) = 2.2v (for Version 1.xx) 2.1v (for Version 2.xx) Termination Voltage = Auto 1.2v HT: Auto NB Vcore: 1.5v SB Vcore: Auto CPU VTT: Auto As I mentioned before, this is my first self build PC - the hardware worked fine but I really need some serious help with all these confusing BIOS-settings. Thanks for your understanding. Link to comment Share on other sites More sharing options...
DerekT Posted November 16, 2007 Share Posted November 16, 2007 You are limited by the population of 4 DRAM banks. The memory controller can not keep up with the extra DRAM at the rated 8500 speed. You will need to drop the speed of the DRAM from 1066Mhz to 800Mhz. If you had purchased 4 X 1024MB of PC6400 (800Mhz) DRAM, then you would have had to drop to PC5300 (667MHz) DRAM, etc. 2 X 2048 will not issue this problem. This is a problem of all 4 banks being populated. Think of it this way. If you have a small phone book, then when you go into the index to find the page where you will find the phone number you are doing so at a certain speed due to the pages of the Index. Then you have to drive through the pages to get to the number. Now if your index is twice as large and the pages twice as many, then it takes longer to access and load the data. Now DRAM has a Strobe and the length of the strobe is how long the rows and columns can be left open before they must be refreshed. There is not enough time for the dram to be refreshed and then accessed with 4GB at the full access speed of the DRAM. The chipsets are optimized for 2GB, not 4GB and for 2 DRAM slots, not 4 DRAM slots populated. You can overclock the FSB (and hence the Memory Controller Hub = MCH) to gain some extra bandwidth and thus access the capabilities of the DRAM since the chipset is now clocked up. Usually when you clock up the FSB and concurrently the Memory Controller Hub (MCH) you need to raise the voltages of the CPU/MCH a bit as well. Download memtest from http://www.memtest.org and extract the ISO image. Burn the ISO image to an CD-ROM disk. Enter your BIOS Setup Utility and enter these settings: I assume you have an X6800? Memory TimingFSB - Memory Clock Mode: Unlinked CPU FSB: 266 CPU Multi: 11 DDR FSB: 800 tCL: 5 tRCD: 5 tRP: 5 tRAS: 15 Advanced Memory Settings tRRD: 5 tRC: 24 tWR: 6 tWTR: 8 tREF: AUTO tRD: 7 tRFC: 42 Async Latency: AUTO CMD: 2T Voltages Vcore = Auto Vdimm (DRAM Voltage) = 2.2v (for v1.xx) or 2.1v (for v2.xx) Termination Voltage = 1.4v 1.2v HT: 1.3v NB Vcore: 1.45v SB Vcore: 1.50v CPU VTT: 1.25v Leave all other settings to Auto Boot to the optical drive with the memtest disk and allow for two full passes. If you find errors. Remove one stick and test with one stick. Replace with the other stick and test. Once you find stability, then you can choose to upclock the CPU --> Northbridge --> DRAM and find higher throughput. Otherwise, you will be held back by the populating of 4 DRAM banks. Results?

Corsair Employees RAM GUY Posted November 16, 2007 Corsair Employees Share Posted November 16, 2007 You can get the tested setting from the link in SpecMikes or my signature and then look in the user manual section 4 for the settings and how to change them.

and_boy Posted December 26, 2007 Share Posted December 26, 2007 Hi everyone, Just not to create a new topic I am wondering, will these settings work with Intel Q6600 to make 4GB Corsair Dominator CM2X1024-8500C5D run @ 800 MHz? :confused: Memory Timing FSB - Memory Clock Mode: Unlinked CPU FSB: 266 CPU Multi: 11 DDR FSB: 800 tCL: 5 tRCD: 5 tRP: 5 tRAS: 15 Advanced Memory Settings tRRD: 5 tRC: 24 tWR: 6 tWTR: 8 tREF: AUTO tRD: 7 tRFC: 42 Async Latency: AUTO CMD: 2T Voltages Vcore = Auto Vdimm (DRAM Voltage) = 2.2v (for v1.xx) or 2.1v (for v2.xx) Termination Voltage = 1.4v 1.2v HT: 1.3v NB Vcore: 1.45v SB Vcore: 1.50v CPU VTT: 1.25v Leave all other settings to Auto Thanks Link to comment Share on other sites More sharing options...

and_boy Posted December 26, 2007 Share Posted December 26, 2007 Thanks. One more question. If I overlock Q6600 @ 3 GHz do I need to change these settings or I I can just leave them? Link to comment Share on other sites More sharing options...
bigbuck08 Posted December 26, 2007 Share Posted December 26, 2007 You would have to change the CPU FSB and maybe the Multiplier, possibly the Vcore volatge too. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 26, 2007 Corsair Employees Share Posted December 26, 2007 You may have to, but I would try it first and only make changes as needed. Link to comment Share on other sites More sharing options...
