Well after giving these OCAU forums a pretty hard bashing and thorough grilling trying to get to the bottom of various issues regarding my upgrade from my old P4 Prescott (SunCore) 3.0GHz @ 3.5GHz CPU to a Intel Core2Duo E6600. The initial plan was to do a cheap upgrade by using a Asrock ConRoe865PE, as it was the only Motherboard that supported a Conroe, + 4 slots of DDR1 Memory + AGP. There were downsides to this plan because the motherboard only has 2 SATA connections and I have 3 SATA drives. Anyhow, my birthday rolls around and I ended up with more cash than I thought I was going to have, so I went the whole hog and upgraded the CPU, Motherboard, RAM & Video Card. Final Parts List: Intel E6600 Core2Duo CPU $455 from TI Computers St Leonards Gigabyte 965P-DS3P Revision 3.3 $238 from TI Computers St Leonards Corsair TWIN2X2048-C6400C4 $372 from SkyComp Sydney City Gigabyte GV-NX76T256D-RH GeForce 6600GT Video Card 256MB $200 from Orange IT Sydney City Total Cost: $1,265.00 Although the memory is good, I was hoping not to pay that much, and holding out hope of getting some A-Data DDR2-800 RAM for well under $300, but of course the dodgy website advertising A-Data DDR2-800 RAM for under $300 doesn't have any in stock, with only the vague promise of some time next week for new stock to arrive. Anyhow with budget a bit blown out by the RAM, I had to settle for the cheaper Video Card, which wasn't all that bad a deal since its a silent pipe, and it came with Civilisation 4 which the girlfriend will love. Who incidentially, is getting all my old hardware, which is about as much of an upgrade for her, as this upgrade is for me in terms of performance. So, I hadn't formatted for at least 2 years (I'm completely over formatting every other week thank you very much), so reformatting for me is a major issue. I ended up using nLite combined with Ryans Update Pack and this gave me a fairly good install of Windows XP without having to do too many updates (christ Microsoft release service pack 3 already FFS) but was hamstrung trying to get AHCI working correctly since the usual Press F6 method of installing storage drivers was refusing to work for me. Finally got over all that using nLite again and now slowly getting my PC back into shape. Anyhow you can see in the last picture I've not yet installed the water cooling. That is because the waterblock won't fit correctly on this motherboard because of that line of capacitors at the back of the CPU socket. Luckily Radiical Computing is going to come to my rescue by machining a 10mm groove into the end of the water block to give me the clearance I need for those capacitors, so I can get my water cooling going once again. I haven't tried to really overclock yet, just playing around, but a few things strike me as odd. 1. As far as I can tell with this Motherboard BIOS (I've upgraded to the latest from Gigabyte website) I cannot adjust any memory timings whatsoever. Is that correct? How do I get the memory timings to show up so they can be adjusted in BIOS? How do you change the memory timings? 2. My memory is running 266 x 3 = 800MHz but CPU-Z says my memory is running at 5-5-5-18 even though the memory is rated for 4-4-4-12 for DDR2-800 WTF?? 3. What the hell do I have to disable/change in this BIOS to make the CPU overlock properly, without it underclocking? 4. What the hell is HPET in BIOS? All I get is High Precision Timer, but no actual explanation of what it is or does. Umm thats about it for now. I can't go for those more extreme overclocks until I get my water cooling back in shape, which is not going to happen for over a week at least. Thanks for reading, and I hope this has some useful information for somebody.
