svl7 Posted July 27, 2011 Author Share Posted July 27, 2011 This CPU can really do crazy stuff when there's enough voltage and power (and cooling, lol): Vantage and the 1024M wprime were done at 30x, the 32M at 30x with a raised BCLK (137.8MHz). 3 Quote Link to comment Share on other sites More sharing options...
iloveb00bs Posted July 28, 2011 Share Posted July 28, 2011 man thats friggin sweet!!!! + rep Quote Link to comment Share on other sites More sharing options...
svl7 Posted July 28, 2011 Author Share Posted July 28, 2011 Thanks bro! I was hoping to crack 16k Vantage, but my GPU was always at 400/900... no idea why. Tried several drivers etc... haven't found the solution. Will investigate a bit, but for the moment I'm annoyed, was hoping for a cool bench session and I only had troubles. At least I managed some crazy CPU scores. Quote Link to comment Share on other sites More sharing options...
iloveb00bs Posted July 28, 2011 Share Posted July 28, 2011 thats beyond crazy , dam that score is friggin amazing. just got my new r3 in today, but been busy as heck so i haven't had the chance to mess with it yet. one thing i noticed though is the bottom panel and heatsink is improved. not gonna have benches for awhile, too busy with family stuff.

svl7 Posted July 28, 2011 Author Share Posted July 28, 2011 Yeah, quite a killer score... heat was overkill as well. Without dice I think I would've melted the mobo. Once you have some time, let us see some pics of your beast when you have it set up with the green casing. And some pics of the interior...

mw86 Posted July 28, 2011 Share Posted July 28, 2011 SVL7 did you know how close you are to DR650SE's 1024M score for wprime and thats with DICE... I bow to you lol! Quote Link to comment Share on other sites More sharing options...
svl7 Posted July 28, 2011 Author Share Posted July 28, 2011 SVL7 did you know how close you are to DR650SE's 1024M score for wprime and thats with DICE... I bow to you lol!Well, my runs were with dice as well, no chance that I can run 30x with a 200mV core voltage increase without extreme cooling, would've melted my mobo. I tried to beat his 1024M score, but it's pretty hard to find a sweet spot with the BCLK, it always crashed halfway through the test. 30x without BCLK increase was very stable, no crash. 1 Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted July 28, 2011 Founder Share Posted July 28, 2011 did you increase the memory voltage as well? Quote Link to comment Share on other sites More sharing options...
svl7 Posted July 28, 2011 Author Share Posted July 28, 2011 did you increase the memory voltage as well? No, I tried this once with the M15x and ended up in an infinite boot loop... my system doesn't seem to like it, and I'm still on stock RAM Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted July 28, 2011 Founder Share Posted July 28, 2011 yeah you will probably need to increase the voltage there as well cause those crashes may be due to the memory. Quote Link to comment Share on other sites More sharing options...
svl7 Posted July 28, 2011 Author Share Posted July 28, 2011 Yes, most of the time it was the memory crashing, maybe the HyperX memory will accept the voltage increase. I'll probably do some more CPU benches when I got the new RAM. Quote Link to comment Share on other sites More sharing options...
widezu69 Posted July 28, 2011 Share Posted July 28, 2011 I run 1.6v on my DaneElec value ram with 9-9-9 timings. Hynix ram chips. 1 Quote Link to comment Share on other sites More sharing options...
DR650SE Posted September 17, 2011 Share Posted September 17, 2011 Hmm, this would definately help me get some global boints with my 540M. I wonder if the solder wire I have is thin enough. Quote Link to comment Share on other sites More sharing options...
svl7 Posted September 17, 2011 Author Share Posted September 17, 2011 The thinnest solder wire I have is 0.5mm in diameter and that's definitely too big. Also usually solder wire is rather fragile, you don't want the wire to break when you insert the CPU. Quote Link to comment Share on other sites More sharing options...
DR650SE Posted September 17, 2011 Share Posted September 17, 2011 (edited) Yea thats what I was thinking about. It's very fragile. Where did you get the copper braid? I might be able to strip some CAT 5 line. If I can get this done, it will mean rerunning benchmarks on the 520M, 540M, and other chips. Not sure if the 540 will be an issue with heat, but breaking out the dice cup would be necessary for the 940XM.Just hit me, I can use speaker wire. I think essentially your just connecting the pins right? I mean when you jump the two holes, the socket still slides into place once the chip is locked in so essentially it appears your just jumping the pins.

svl7 Posted September 17, 2011 Author Share Posted September 17, 2011 Where did you get the copper braid? I used a wire from a defective power adapter: It's copper, pretty thin, but much less fragile than for example solder wire. For the +200mV mod I used two pieces as you can see on the picture in the first post. The second time I used only one, works fine. 2 Quote Link to comment Share on other sites More sharing options...
DR650SE Posted September 17, 2011 Share Posted September 17, 2011 Im going to try this tonight. Looks like the easiest thing. Biggest pain is diassembling the system. Ill bet i can put up some big numbers with my 540m. That thing is a beast overclocker. Ill put it on dice if temps are crazy. 1 Quote Link to comment Share on other sites More sharing options...
svl7 Posted September 17, 2011 Author Share Posted September 17, 2011 As I told you in the PM, you might have to measure the voltage of the 540m at load first, if it is significantly lower than the voltage of the 920xm, the VID4 mod might have no effect at all and may require a different pin to increase the core voltage.For example if the max stock voltage of the 540m is somewhere between 1.0 and 1.1V, the VID4 is already set to 0, so this mod wouldn't have any effect at all.

DR650SE Posted September 17, 2011 Share Posted September 17, 2011 Hmm, Thats true. Don't really have much way at the moment to measure the voltage. Quote Link to comment Share on other sites More sharing options...
svl7 Posted September 17, 2011 Author Share Posted September 17, 2011 You need a multimeter and some thin wires, the cool thing is that there are VSS and VCC pins directly at the edge of the socket. They're not the most accurate points for measuring, but more than sufficient. The best would be the VSS_Sense and VCC_Sense pins, the VSS_Sense is at the edge, the VCC_Sense just behind it, which makes it hard to use those two.I simply used a regular VSS and VCC pins, as you can see in the pic here.You could also use the VSS_Sense which is at the edge and just any VCC pin somewhere at the edge.Then start a wprime 1.55 or similar with the max possible thread count and measure the voltage. The value won't be 100% accurate, but a quick look at the VID table will reveal the actual value, just use the one which is next to the one you measured.After this you can figure out one or more suitable pins for the mod. 1 Quote Link to comment Share on other sites More sharing options...
DR650SE Posted September 17, 2011 Share Posted September 17, 2011 (edited) May have to get a multi meter tomorrow. Any sort of documentation that would give the voltage or program that shows it? I know old core 2 chips read voltage in Cpu-z Edited September 17, 2011 by DR650SE Quote Link to comment Share on other sites More sharing options...
svl7 Posted September 17, 2011 Author Share Posted September 17, 2011 No, there's no known way to read out the VID, unclewebb doesn't know how to do it either, there's nothing to be found about this in the Intel documentation and there's no program which could read out the VIDs. That's why I've come up with this: -first-gen-intel-core-i7-series-core-voltages.html#post9695"]http://forum.techinferno.com/general-notebook-discussions/827-[solved]-first-gen-intel-core-i7-series-core-voltages.html#post9695It's a pita, but it's the only way to do it as far as I know. 1 Quote Link to comment Share on other sites More sharing options...
DR650SE Posted September 18, 2011 Share Posted September 18, 2011 Well tomorrow I'll get a multimeter and feed you my results. Hopefully they will be good. I can get the 540M up over 4GHz, now I want to get it higher because it's the best chip I have for global points. I'll also be picking up some dice tomorrow and bench the chips with that using the dice cup. Heat won't be a factor, So maybe I can use the full 150mV on the chip. Best thing for me to do would be test on the 520M since that will be a stock chip. if it dies, I'll just call dell 1 Quote Link to comment Share on other sites More sharing options...
svl7 Posted September 18, 2011 Author Share Posted September 18, 2011 Cool, sounds like a great plan! Looking forward to seeing your results!! Quote Link to comment Share on other sites More sharing options...
DR650SE Posted September 18, 2011 Share Posted September 18, 2011 Thanks. Going to be doing it tomorrow afternoon. Also downloaded team viewer. May let johnksss tinker with it a bit. If this works i should be able to pick up some hwbot boints Your free to tinker with it too as soon as i get the vmod done. It'll probably be after 1pm my time on the east coast.
