Ok I'm still testing my new 2600-M chip, and its currently running at... 173 x 13.5 @ 1.55v (2333MHz) (36C under 10% load, MAX load is 44C) (STOCK for this chip is 166 x 12.5 @ 1.45v) Memory is... PC3500 RAM 1Gb Dual-Channel DDR (running at 216MHz according to BIOS) CAS - 2.5T RAS to CAS Delay - 3T RAS Precharge - 3T RAS Active Time 7T Motherboard is DFI LanParty NFII Ultra-B (latest BIOS revision) Currently, I'm getting 2472 MB/s READ, and 1022 MB/s WRITE speed from benchmarking the RAM. CPU also seems quite stable at these settings with the regular air-cooler & also the temps are quite low! I'm looking at trying to get a bit more though out of it with this air-cooler. So I'm mainly after a few suggestions on what settings I should try, or if anything above seems wrong, then what the4y should be. Cheers Paul
Firstly, get the ram sync rather than async m8, will improve things a lot. (change the ratio, to 1:1) and increase the FSB to 216 that should imprive things. Drop of multi will be required though to maintaint the same clock speed) 44 load is fine, you should be ok up to ~55, so keep increasing the multi and voltage and see how far it'll go....
Ok new settings... FSB is now at 216MHz... (216MHz x 10 @ 1.6v) RAM is now at 433MHz (3,4,4,9) Read speads are now 3136 MB/s Write speads are now 1245 MB/s Temp (10% AVG idle) 36C (Surely not!) Load is 46C... Super PI took 47secs on previous settings, now takes 46 seconds (not bad seens CPU is now at 2166MHz (167MHz slower!) Question now though, can I take the multiplier up much... I need to do more tests though see how stable this is...
Multi should go up a little yes, you have some headroom for the temps. As for the ram, what voltage are you running it on? Will it not manage 2.5,3,3,11 (use 11 rather than 9 its faster on Nforce based systems)
Ok RAM timings are now 2.5,3,3,11... voltage is currently 2.5v. Read speed now 3252 MB/s Write speed now 1271 MB/s Those little tweeks certainly have made a difference! Looking at the charts in AIDA32 aswell, it says its performing better than the Athlon 3200+ XP which is there by over 500MB/s read & 150MB/s write! Champion! Also did a quick 30-min Prime test (the 2nd option in the Torture test)... Load temp reached 49C and system temnp was 40C... I 'might' be able to get away with increasing the multiplier to 10.5, maybe even 11 (touch & go though) before the air-cooler reaches its limit! I can't get 3dmark 2001SE to run though it keeps complaining that I need DirectX 8.1,m but I have 9.0b... Tried re-installing 3dmark, but no joy
Ouch, case is a tad warm, what do you have in the way of cooling? Best bet is to run Prime for ~6hours to check stability and temps. Running those timings on 2.5v, interesting this could mean you could run 2,2,2,11 at 216 fsb with a little more juice, maybe up to 225 if you are willing to run 2.8-2.9v through the ram. What brand is it, do you know?
At the moment, the northbridge has the stock cooling (passive, no fan), CPU is a cheap £12 copper-cooler I got to do some 'short' tests. Ram is KingMax PC3500 (basically what budget could reach to this month). I will be fully watercooling this machine though, I'm just having a few problems getting the blocks made up, but I'm also debating watercooling the RAM (never seen it done, wondering if it would be beneficial). I'm going to stick a different cooler on the n/b toimorrow though which has a fan & test it some more then... Basically for the time being I want to bring this within an inch of its life to see what can be achieved via air-cooling & then see how much of an increase can be got with fully watercooling. I'll keep those ram timings & voltage in mind though for when I get some sort of cooling for it!
Might be an idea to fully sink the mosfets on the mobo m8, some do get VERY hot... The lanparty will go a long way thanks to the good bios options As for the ram, it seems you've got some good stuff, had to RMA my OCZ EL 3500, would run 2.5,3,3,7 at 216 on 2.7v see this post by BigZ for sinking details http://forums.bit-tech.net/showpost.php?p=582525&postcount=16 Would deff be worth picking up a bios saviour if you can as well m8...
Looking at the post & picture from BigZ... what sort of cooling would you say should be ok? Just looking at those RAM shim things which you can buy, reckon it would be ok to use those? I left Prime95 running all night last night, temps peaked at 49.5C all night & it returned no errors, system temps stayed same at 40C load though.
I chopped up an old P200 sink and an old heastink from a PSU for the fets around the dimms (prevents snagging) which will be thermal expoxied on when i can be assed.... (need to count up how many i need, but may well have some spare if you need them......) Seems nice and stable then, you can probably OC further, but the temps are ~ the max now. Best bet is to try increasing the FSB and dropping the multi to get some more mem bandwidth
2.2.2.11 wouldn't post & tried voltage upto 2.8 to get it. Now increased CPU voltage to 1.65 & multi to 10.5, so now 216x10.5 (2268MHz) Also installed WebTemp & MBM5 on the machine so I can fully log everything which is going on! Gona let it idle for about half-an-hour now get low readings & then push it a bit... I'm curious though, the CPU Diode temps, I guess Mobile Athlons have an internal-temp sensor... Just looking at it peaking there a bit, it seems all over the place! Could anyone verify what it actually is & where its located please?? It's still air-cooled mind!
Nice Is that the free version of webtemp? If so might dgive it a shot... Does it require FTP access at all? My infinity does the same m8, I tend to ignore that sensor (you can see why lol) There is a small diode in the ZIF, under the cpu which records the temps, not quite as accurate as the on chip one, but the finger test usally shows how accurate it is
No I paid for this one, the free one doesn't record as much data, but its definately worth the few £££'s IMO! And yeah it does need FTP Access to upload pictures, but is easy enough to configure! Right I've turned off the Diode readings, I see what you mean, I just did SuperPI test & it shot to 76C!!! CPU temp reached 41C though, so not too bad for a 1mbPI! Going to leave it running Prime for a bit now, would be interesting to see how these temps/settings fair... **EDIT** Computer just powered itself off, think the BIOS must be reading the diode temp as the actual CPU temp or there is some sort of fail-safe built into the AMD chip, as as soon as the diode temp reached 100, it shut down. Not sure if there is anyway to circumvent this, so will have a look into it sometime. CPU now at 216x10@1.6 (as tested last night), will try upping FSB @ 1MHz increments till I reach 220 id its possible, but I think I'm pretty much at the limit of air-cooling! Oooooh this is fun!
power off completely... seems ok now multi is back down at 10, but the diode temp hasn't gone above 80 yet (was just over 100 when powered off last time)
Sounds like the shutoff temp is read from the diode rather than the socket... Its set to 110 on mine (so would probably be the same in yours) the read issues may well be fixed though in a bios update, Once the bios saviour arrives will get down to testing Might give webtemp a go, as long as my ftp is ok (uni connection, ftp is random lol) Keep upping the FSB, you should be ok to 3v on the ram, add an 80mm over the northbridge/ram area if you can though, the northbridge gets very toasty.... What PSU are you using m8? lines seem a touch on the low side (nothing to worry about, just a little lower than is ideal)
Shutoff temp is set to 100, but I can't figure out how to adjust it as its locked out in the BIOS also running the latest bios update from DFI & when I was still running the original bios, it was still locked! I 'dont' think I will be able to get much more out of this chip tbh with the aircooler, as with this 100 limit on the shutdown temp & also Prime was playing up a bit on the 1Mb torture-test before when I was trying to run at 218FSB, but everything else seemed to be fine, no crashes anywhere, no problems in any games or any other prime tests, was just that 1! So was a bit weird I thought Still want to try and break 2.2GHz though before I start the watercooling... Maybe it just aint gona be possible but if I fry the chip in the process, I'll just buy another! Not like its gona cost an arm & a leg to get like the 64bit AMD's (main reason I stuck to the 32bit route, cost!) Also going to try design some sort of custom-cooler for the mosfets, as 'might' have enough copper left over once I've got the waterblocks made up.
Some of the betas might have the adjustment, will have to wait til the saviour arrrives to find out though, fingers crossed tomorrow or monday You should be able to hit 2.2ghz tbh m8, try dropping the fsb to 166 ( i know this will harm mem bandwidth) and see if you can get any further cpu wise.... Some of the Xp-m's dont like fsb however i dont think this is an issue with the infinities....
I was having trouble running the xp-m at 200fsb with the multi set to 10 like it is now, but 216 seems to be no proble at all Dont wana drop the memory bandwidth if pos as got greedy & the increase from the first values in this thread is really noticeable! But if I have to I will, jkust hope the speed increase makes up for it! I 'think' I might be able to push 220fsb (risky), the RAM should take it & I can relax the timings a bit to try get it more stable, as at the moment, I've got the CPU timings set to aggressive, so will try some different ones (I never actually considered altering that before tbh, so hopefully it will help!) I've got a ~60CFM 80mm fan somewhere, so will slap that on the cpu cooler aswell to replace the pitiful effort which is on it atm!
Basically m8 you only need to drop the FSB to test wether the CPU "likes" FSB or not... IF it does say 2.4ghz on 166 fsb but only 2ghx on 220, then you can "mod" the CPU to run at a higher default FSB, thus allowing 220 at 2.4ghz (in theory anyways)
