desikida Posted December 16, 2006 Share Posted December 16, 2006 Hi guys - These forums seem very active and have had some questions answered in the past from reading other posts - Hoping anyone of ya out there could give me a hand with OC'ing cpu/ram ... having some problems and queries. RIG Setup is: P5N32-SLI SE DELUXE Intel Pentium D 950 800FSB base 3.4ghz CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 PC2 6400 TWIN2X2048-6400PRO 5-5-5-12 1.9V 8800 GTX BFG Video Card (originally thought I had issues with the 8800 but alas it does seem flawless and was simply/is still being extremely bottlenecked by my cpu) [side note* for 3Dmark06 OCed cpu at ~890FSB I get around 8300-8400 points with a OC cpu score of about ~1900 after my queries are remedied/learn more I plan to OC it to 4 ghz ~940FSB] Well I've been OCing and flashing my bios to the most recent 0603 and what not and have been able to get my system to OC manually and with preselected profile settings etc. Still not very good at it (barely know what exactly I'm doing) but I use this "linked" command with OCing in the bios so that I only adjust the FSB speed i.e. 890 mhz then the memory is auto adjusted and clock of the cpu as well bringing it up to about 3.7ghz. **note the SPD always stays the same for one being ~270 and the other ~400 adding to ~667 mhz.. I asked The magnificent RAMguy about this and that is due to the processor.. the processor having an FSB of 800 mhz will only support 667 mhz timed ram... so that's kinda a waste of ram until I get a better cpu..wish I had known that before, but live and learn, it shouldn't adversely affect me too badly..i hope.** Now my problem is as the screen shots below will show you while using preset profile command set for ~FSB890 mhz I get results that look like this (pay attention to memory tab as this is where I am confused and baffled at the results) http://img.photobucket.com/albums/v678/desikida/CpuzOCProfile890FSB.jpg Now using a manually linked command and manually putting in ~890mhzFSB and leaving the computer to auto adjust memory I get this: http://img.photobucket.com/albums/v678/desikida/cpuzOCmanually890fsb.jpg And finally no overclock at all it looks like this: http://img.photobucket.com/albums/v678/desikida/cpuNOToc.jpg Now my questions: 1) Looking at solely the memory tab the frequency reads i.e. for one of them read 449mhz does that mean total 449 mhz or is it double or.. what? I’m not sure if that’s high or very very low, takes into account one DIMM or both etc.. mainly confused cause the SPD reads 2 different dimms I believe thus one is rated ~400 other ~270 so does the memory tab show which one.. or both.. (if both that must be horrid!) etc??. 2) Whenever I over-clock at all and allow the memory do auto adjust ( I do this namely because whenever I try to manipulate the memory/clocks to say 4-4-4.. or something it never loads up so I just leave it on auto, there are values you can enter for the memory if you choose manual which start at 800 like the FSB, but really don’t understand what I should enter there etc.) Why when I OC my FSB do the timings go up (i.e. worse) instead of going down, though the frequency improves? 3) I had read briefly that to OC correctly it has to do with the multiplier of your cpu, and the FSB:DRAM ratio – Has anyone knowledge on this to share as it was not explained.. it just said something similar to the fact they are related 4) I’m sure I’m doing something wrong so any advice would be most welcome for this. I.e. what do I want the memory to look like after OCing the FSB, any other settings to try.. a good combo of settings.. or really just anything .. the more specific the better! 5) There is an "enable/disable optimal memory mode" option in the bios.. same with CPU, they are defaulted to disabled. I read about them but I still fail to understand/comprehend the explanations - Should I leave them disabled? Any help, suggestions, anything would be very helpful for a newbie OCer I've managed to get this far from the ASUS manual, other forum posts, tutorials and what have you. :confused: EDIT: **oh and another side note I also ran diagnostics using memtest86+ and after 45 min - an hour or so I passed with zero errors so the RAM should be functioning correctly, although still confused as to why it said memory was 200 mhz (ddr400) .. Does that mean it was reading each dimm at 400 mhz due to the 'ddr' and thus total of 800 mhz or is it only reading each at 200mhz.. ??.. it sounds suspicious and frightening.** EDITx2: Read another OCing guide, but again doesn't cover specifics queried above, in fact, it added questions to the list such as taking into consideration the CPU Voltage and Ram Voltage. How much.. to increase the cpu Voltage with xx increase in FSB.. etc? Also made me more confused with the multiplier.. hopefully will not have to change multiplier as there is no setting I have found in this mobo's bios for it, just FSB, Memory, Voltages (all on auto as they do not display exactly what they are set to in the bios) Link to comment Share on other sites More sharing options...
