smarsh1966 Posted October 13, 2007 Share Posted October 13, 2007 System: Asus P5N32-E SLI (Bios 1205) Intel QX6800 (Quad Core 2.93Ghz) 2GB of latest PC2-8500 Dominator (2.1V) 2x 8800GTX cards (bridged) 850W PSU Dual 74GB Raptors running in RAID0 Antec 900 Case Vista Ultimate 32Bit (all pacthed up) Creative Fatal1ty Pro PCI card So, all components seem to be screaming, except for the RAM: Sandra (latest download of lite) reports: Int Buff'd iSSE2 Memory Bandwidth : 5589 MB/s Float Buff'd iSSE2 Memory Bandwidth : 5573 MB/s Results Interpretation : Higher index values are better. Windows Experience Index Current Chipset/Memory : 5.3 The current timings are : 5-4-4-12 2T with TrC of 16 Voltage is Auto, but reporting about 2.1V...FSB linked running at 1066Mhz BIOS reports that it's running at 1066Mhz and DDR mode. Seem like my timing values are pretty good, but don't seem to get the benchmarks other people seem to be getting around here... i would expect about 8000 MB/s or so.... Any ideas? More Info: Enabled SLI ready in BIOS and set to MAX... most other things in BIOS like Spreadspectrum, Virtual, enhaced bit, disabled.... even disabled legacy USB support.... Thanks!

DerekT Posted October 13, 2007 Share Posted October 13, 2007 Download Memtest from http://www.memtest.org. Burn the ISO image to optical drive and boot to the optical drive. What is the L1 and L2 caches runing at: What is the "Memory" speed running at? What do the "Settings" show? Link to comment Share on other sites More sharing options...

DerekT Posted October 13, 2007 Share Posted October 13, 2007 By 'Settings' which settings were you looking for, since Memtest does not show other options. The Dual Channel Mode should be shown. Are you certain you are running in Dual Channel Mode? Try these settings and run Memtest again. Results?

smarsh1966 Posted October 13, 2007 Author Share Posted October 13, 2007 Whn the BIOS posts, it reports 1066MHZ and Dual Data Rate Mode Enabled.... I know, it almost seems as though DDR is not enabled, i also have tried moving the RAM from the white slots to the blue with similar results... i will try your BIOS settings and report back... thanks.

DDR is not configurable. I am speaking of Dual Channel Mode. Does Memtest show 128bit or 64bit? Link to comment Share on other sites More sharing options...
smarsh1966 Posted October 13, 2007 Author Share Posted October 13, 2007 you can certainly disable it by not placing them in the correct slots.... again Mem Test only reports what i showed before.... i tried the BIOS settings you posted and a found a few things: 1. CPU multiplier of 12 would OC the processor. The Std multiplier for this CPU is 11 (Since i cannot find the option to set the FSB at 266) 2. the TWTR cannot be set to 10, max setting in BIOS is 7 3. tREF cannot be set to 7.8us, it has either 1or 2 or auto. What version of memtest do you run, i have the latest ISO from the site and that is what it is reporting.... Still, MemTest reports the Memory the same way... I have a feeling we are dealing with different Mobo's the P5N32-E SLI i have is 680i chipset and BIOS 1205..... Any ideas.... the timings seems to reflect that mem is NOT running in DDR mode, yet when the BIOS posts it clearly shows it's running in DDR. i will post an image of the BIOS post shortly... and Mem Test running...

smarsh1966 Posted October 13, 2007 Author Share Posted October 13, 2007 here are the images of the POST and Mem Test... as you can tell, it change from a quad core to a dual core! and thinks Hyperthreading is enabled...... this is whacked..... i'm going to reset the BIOS via the jumper and start again.

smarsh1966 Posted October 13, 2007 Author Share Posted October 13, 2007 i reset the BIOS and set the CPU setting s the way i had them, now it posts the way i think it should..... Link to comment Share on other sites More sharing options...
DerekT Posted October 13, 2007 Share Posted October 13, 2007 you can certainly disable it by not placing them in the correct slots.... again Mem Test only reports what i showed before.... That is Dual Channel Mode, NOT DDR mode which is Double Data Rate Mode. DDR Mode is NOT configurable and runs on both the rise and fall of the sine signal. Dual Channel Mode is configurable. It is the interleaving of the channels. In single-channel mode, the Memory Controller moves 64 bits of data at a time whereas in dual-channel mode, it can move double that amount or 128 bits of data in optimal situations. i tried the BIOS settings you posted and a found a few things: 1. CPU multiplier of 12 would OC the processor. The Std multiplier for this CPU is 11 (Since i cannot find the option to set the FSB at 266) [/Quote] Yes, I pressed the wrong key. 11 is default. 2. the TWTR cannot be set to 10, max setting in BIOS is 7 3. tREF cannot be set to 7.8us, it has either 1or 2 or auto. Set them both to Auto on your board then. What version of memtest do you run, i have the latest ISO from the site and that is what it is reporting.... Still, MemTest reports the Memory the same way... I have a feeling we are dealing with different Mobo's the P5N32-E SLI i have is 680i chipset and BIOS 1205..... I have worked with the Striker board more than a few times and they are quite alike so I am referencing my work from that board. Memtest 1.70. Memtest is showing nothing for your chipset so it can not query for Dual Channel Mode. Download CPU-z: http://www.cpuid.com/download/cpu-z-141.zip Please print screen and post the shot for CPU and Memory. You can use photobucket.com to upload them. Any ideas.... the timings seems to reflect that mem is NOT running in DDR mode, yet when the BIOS posts it clearly shows it's running in DDR. You are confusing DDR with Dual Channel. They are not the same things. Edit: Your post shows that the DDR is running in Dual Channel Mode. What does memtest show for bandwidth?

DerekT Posted October 13, 2007 Share Posted October 13, 2007 It looks all correct to me. The dump does not show Dual Channel Enabled but your Boot screen does. That link I posted shows where your sysem would be with DDR2 800 @ 5237MB/s and you are at 5589 with your 1066. Probably all at stock is doing this. Remember that when you overclock, you also increase all the busses which will show greater throughput. Here's one I am working on right now. It's at 3.4GHz with 1066 DRAM at 1150Mhz and 5-5-5-12 on P5K-E. A 9300MB/s read. http://i93.photobucket.com/albums/l74/Barkiss1/test.jpg Link to comment Share on other sites More sharing options...

DerekT Posted October 13, 2007 Share Posted October 13, 2007 Ahhh, so my numbers are pretty much in line with the test.... should i not expect better numbers with 8500? You're still running at defaults and you can not compare your default FSB with overclocked ones. You will easily lose out. You are running faster than the 5200MB/s @ 800Mhz.
