\nYeah that’s right… 6300 3DMarks in 3DMark06 on standard settings…<\/p>\n

System Config:<\/b>
\nDell XPS M1530
\nIntel\u00ae Core\u21222 Duo Processor T7250 (2M Cache, 2.00 GHz, 800 MHz FSB)
\nNVIDIA GeForce 8600M GT 256MB GDDR3 (OC@680\/990) 195.62 drivers
\n3.00 GB RAM \/ 250GB 5200 rpm HDD
\nWindows 7 Ultimate Build 7600<\/p>\n

<\/a>Default GDDR3 8600M GT’s Clocks are 475\/702 which give a Base Score of ~4200\u00a03DMarks… That is a monstrous\u00a050% increase for an approximate 40% overclock! And the amazing thing is that there’s only about a 4\u00baC change in peak temperatures…\u00a0Have a look at the babe…<\/p>\n

\"\"<\/a><\/div>\n

This babe plays Crysis 2 at a passable 30fps with Advanced Settings@1024×768… Astounding for a 4 year old laptop!<\/p>\n

PS: To be a little on the safe side, it would be advisable to overclock to 650\/950 or so… That is considering the game crashed with 690\/990 clocks in less than a minute…<\/p>\n

(edit: 05\/05 2011)<\/b> After loads of gaming\u2014almost done with Crysis 2, played quite a bit of SimCity 4, restarted Unreal Tournament, even took a jab at CS again\u2014I must say, it is completely stable for all ranges of games at 630\/940…<\/p>\n

I’ve also got a lot of traffic querying for original clocks and best drivers. So here’s a bit of info:
\nThe 8600M GT comes (or rather, came) in 2 variants\u2014one with DDR2, and another with GDDR3. The bandwidth difference makes the Effective Memory Clock at 800Mhz (400×2) for DDR2 and 1404Mhz (702×2) for GDDR3. The rest of the clocks are same.. So here we go:<\/p>\n

\n\n\n\n\n\n\n\n
<\/td>\nDDR2<\/b><\/td>\nGDDR3<\/b><\/td>\n<\/tr>\n<\/thead>\n
Core<\/b><\/td>\n475<\/td>\n475<\/td>\n<\/tr>\n
Shader<\/b><\/td>\n950<\/td>\n950<\/td>\n<\/tr>\n
Memory<\/b><\/td>\n400<\/td>\n702<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

And as for the best drivers, I have noticed that 195.62 drivers I use here tend to be unstable, and specially so for games like SimCity 4. The latest nVidia Verde drivers\u2014267.76\u2014did fine too. In fact, I have them on right now…<\/p>\n","protected":false},"excerpt":{"rendered":"
