Hi, just registered on this forum (first post ), been on futuremark forums for a while and just wondered what kind of overclocks you are getting at the mo. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ My best so far on this Abit NF7-S V2.0 / Corsair TWINX3200LLPT v1.2 is 246FSBx10 gives me 3778/3539 in sandra. The highest i've got to 3Dmark2K1 to complete a bench so far is 240x10. Heres a pic of 246x10: When I first got the board it hit 220 max, i then did a L12 socket mod* (see lower down about L12 mod), and hit 236x10 with a MX440 in (the with 4600 it wouldn't post and thought is was the PSU) determined to get 236x10 with the 4600 i though my ENERMAX 460W should be more than enought so I gave the AGP more volts (1.7v) and upped the freq to 99MHz (Please be advised I wouldn't recommend high AGP freqs on ATi Radeons anything over 73/74MHz could damge the card, it's fine however for nV cards) and hey presto windows . It appears that the higher FSB was screwing up the AGP interface so the higher freq and voltage gave it what it needed. Not fully satified I tried 240 and nothing so i switched to a 9x multi and it booted . I asked around and apparently the Abit bios 10 (first release) enabled the high multis at higher FSB so I flashed down to 10 (using flashmenu btw) and it worked . So I was well pleased with that but as overclockers know your never satisfied so I went for the daddy of all NF2 overclocks 250FSB in sync at 500MHz DDR with CAS2 timings . I lowered the multi to 9x (i know this chip does 2460MHz max, 2500MHz was asking too much without better cooling and a lot more volts hence the 9x multi) I upped the AGP volts to 1.8v, set to 250FSB and re-booted. *Crossed fingers* and in 15secs flat I was greeted by windows opened CPU-Z and: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Now to get 240/246/250 my settings were: V-Core: 1.875v VCC (Ram): 2.9v AGP: 1.8v Chipset: 1.7v CPU Interface: Enabled AGP Freq: 99MHz CPU FSB / DRAM Divider: 6/6 Expert ram timings: 11-2-2-2 (From top of screen down, TRAS 11 gives best banwidth for some reason on mine btw ) AGP fastwrites: disabled FSB Spreadspectrum: disabled: CPU Throttling: Disabled Video cacheable: Disabled BIOS cacheable: Enabled (just boots faster) PCI Performance: Enabled All devices (Sound/LAN/SATA/Firewire/FDD/Serial-Parallel Ports: disabled. Note / this is without any voltage or cooling modifications to the board (oh and 250FSB isn't stable ) If your interested in the NF7 V2.0 10 bios heres the link: http://www.motherboardfaqs.com/article.php?8.255 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ *Btw heres a pic of a L12 socket mod for a 133FSB chip: Basically take a tiny piece (single strand) of stripped wire (i used it from an old molex) and bend it into a 'U' shape and link the two socket holes shown where the red lines are on the pic. Clear your CMOS and when you reboot your chip will be detected as a 2700+ by default with a 166FSB and 13x multi so make sure you know you chip and mobo are capable of those settings. As far as I know this works on Nforce 2 mobos not sure of any others . The L12 mod allowed me to boot with FSB's higher than 220 it seems that as a 166FSB chip it has a higher FSB tolarence level which is odd but it works ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I have done some extensive sandra tests with different timings for those with any questions regarding the best ram timings to use here are the results : (Odd thing is 2-2-2-15 performs better than 2-2-2-3 for me, I emphasise 'me' as results may vary they may work for me but could be very different in your rig ) *NF7-S @240FSBx10 (480MHz DDR) 6/6 divider and Dual Ch.* 2-2-2-3 Int: 3661(95% eff.) 2-2-2-3 Float: 3431(89% eff.) 2-2-2-4 Int: 3665(95% eff.) 2-2-2-4 Float: 3430(89% eff.) 2-2-2-5 Int: 3666(95% eff.) 2-2-2-5 Float: 3443(89% eff.) 2-2-2-6 Int: 3675(95% eff.) 2-2-2-6 Float: 3440(89% eff.) 2-2-2-7 Int: 3679(95% eff.) 2-2-2-7 Float: 3446(89% eff.) 2-2-2-8 Int: 3674(95% eff.) 2-2-2-8 Float: 3445(89% eff.) 2-2-2-9 Int: 3686(96% eff.) 2-2-2-9 Float: 3448(89% eff.) 2-2-2-10 Int: 3691(96% eff.) 2-2-2-10 Float: 3452(90% eff.) 2-2-2-11 Int: 3702(96% eff.) 2-2-2-11 Float: 3457(90% eff.) 2-2-2-12 Int: 3698(96% eff.) 2-2-2-12 Float: 3450(89% eff.) 2-2-2-13 Int: 3692(96% eff.) 2-2-2-13 Float: 3445(89% eff.) 2-2-2-14 Int: 3684(96% eff.) 2-2-2-14 Float: 3440(89% eff.) 2-2-2-15 Int: 3681(95% eff.) 2-2-2-15 Float: 3438(89% eff.) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Just interested to see what you guys are getting too P.S if I have broken any forum rule pls let me know as I said 1st post
Thats nice work for a 2100 I havn't been able to overclock for a while since my mATX board doesn't allow voltage adjustments Last decent overclock i got was with my old watercooled rig. XP2400+ at 166x15 = 2490MHz but it took nearly 2 volts and wasn't stable enough for my liking. Where abouts in sheffield are you, i live here/there aswell.
Nice, Welcome to the forums btw My mobo craps out at about 150FSB lol which isn't really worth it. What cooling are you using? Argh cant wait to get back into the overclocking scene, damn my desire for a small plexi pc lol
Thanks for the welcome , sorry to hear about the 150FSB max my old Asus A7V266E did 153FSB max , thats why I got a NF7-S, I had the asus since feb 2002 got this NF7-S a month and half ago was a great move BF1942 is no longer choppy when lots of players on UT2003 is much smoother can up the graphics now as the old/CPU board fell down on the physics engine . As for cooling basically just air the mobo is stock out of the box, standard nb cooling and bare sb . I am using a Coolermaster HHC-001 & Tt Smartfan II 2x intakes 2x case exhausts and a dual fan 92mm/80mm PSU
So noise isn't an issue for you then you planning on investing in watercooling to get the most out of it? i want to build a waterchiller for my next setup for some sub zero goodness
My Barton XP2500 is running at 11.5*200 (for 2300 MHz) at 1.85 V.Core I'm aiming for 2.5ghz, somehow i don't think i'll make 12.5*200, so i'm going to have to hope that this corsair PC3200 will cope with a clock of 220
I just replied to ur thread rav ,erm the noise yes bit loud those settings are generally used for benching/testing and not much else i use 225x10 with CAS2-2-2-11 timings generally as these will run with the CPU on stock volts so the fans can drop down a bit theres nothing more annoying than watching a divx with a WHHHHIIIIIIIINNNNNNEEEEEEE from a 5000rpm fan in the background
P4C 2.4 running at 3.3 with synchronus ram, corsair ddr500 @ ddr550, running at just over stock voltage, 1.63v. stock voltage on the ram (corsair says stock voltage is 2.75v) and its 100% stable (prime95 for 6 hours) i can get quite a bit more but for that i need to bump the voltages up to 1.7vcore and 1.85vdimm, and im perfectly happy with what i have now and the temps are nice and cool.
I read somewhere that the reason why you might be getting better performance with 11 is that adding up the other values gives you 6 (2+2+2=6) BUT, because it is DDR ram, you double it to get 12. The closest value is 11... Don't know if that is why, or you just have a fluke. food for thought though ~Davy
I've added some tests regarding ram timings into the top post. 2-2-2-11 wasn't a fluke i've tested and re-tested and it always gives the best results. TBH i reckon the theory of adding the first 3 up to give the TRAS value is a bit of a myth as far as i'm concerned it's really down to what timings your ram likes and doesn't like
Thats what I'm getting on air. With a Spark 7 cooler with the fan running at the lowest setting ( ~2200rpm ). No other case funs running....
Pretty good there Im getting 2511 out of my 2700, stock 2167 which is pretty good imo. I get about the same as a 3.2ghz p4 so very pleased with the overclock
