Pushed p8700 to 3.4ghz!

I just pushed my p8700 in my g71gx to 3.4ghz!
i didnt think it was possible but after a hour of metro its stable!
CPU-Z Validator 3.1

I love this cpu now! lol

 

Metro is not majorly CPU intensive. Stability is determined from constant high load on the CPU. You want to stress it to see if it can handle it.

Try an hour of Prime 95 torture test and monitor the threads and if it can handle it Prime will confirm if its stable without errors. Im pretty sure they will start throttling. Unless you can adjust the voltage but I am sure the dual cores are locked apart from the X models.

 

Its tweakable to a VERY low extent. i can go to max 1.25v or i can lower it to as low as .8
Would it be better to over or under volt it?
(current is at 1.138 )

 

Play around with it, I wouldnt rule out 3.4ghz being stable just 900mhz increase from stock 2.53ghz is quite a lot and I would be very surprised if it was stable at full load but then again I managed to get my 720QM from 1.6ghz to 2.0ghz stable and that was a big jump for an I7. Stress test full load and keep an eye on the threads to make sure they stay at 100% as they might throttle if there is not enough power reaching the CPU, or it might blue screen and lock up / glitch.

Higher clocks and Higher Loads require more voltage to reach them and more power pumped in means more heat is pumped out. If you can tweak your voltage test it in small increments and stress using Prime 95. You want to try and find a sweet spot which gives good temps but if you not going near the 80/90's at full load with your clocks being that high and they are stable then Bob's your Uncle.

 

Lol thanks

 

what a nice chip you have there!!

got myself free p8600 yesterday best i could validate is 3.2ghz and that's with turbo boost multi so it goes back to 9 multi when i play games

stupid asus cant disable eist.

 

By turbo boost you mean Intel IDA? Because i don't recall that those CPUs have turbo boost.
IDA on the other hand can be forced by ThrottleStop if you want to keep the 200mhz boost on both cores (DualIDA).

Also disabling hpet/platform clock should help with fsb overclock.

 

yeah meant IDA, yeah i was told i cant force it because asus cant disable eist

 

there may be a option in the bios>advanced>cpu

 

Nice, yeah I always wanted to get to atleast 333 on the bus on my G50 and some people have. After 2 cpu's i believe my ram was always the culprit.

Multiplier only goes up on one core and in my past attempts with throttle stop on my T9600 when you select 11 it goes from showing 10.5 to something like 10.65 no clue if it ever worked for anything lol.

 

Wow thats weird?
Your using setFsb right?

 

Talking about the multiplier issue I used throttlestop to try to push the T9600 to the 11 multiplier.

Used SetFSB for the bus overclock yes. I had my original P7450 which even undervolted to .900 would run the same bus speed stable as the T9600 at stock voltage. Increases on voltages for both processors did nothing which leads one to believe the usual weak link was the ram. Never wanted to spend money on it though. Jacobxavier or whoever it was his G50 reached some good bus speed like your G71.

Nice on your gpu btw. I am actually currently running 650/1625/900 the same speeds as a 9600 GT desktop card (9800M has the same shader count, memory bus and type). Stable on desk, 640/1600/900 stable in the field. Been meaning to throw up a thread on it. Burned some 2 hours ati tool + kombuster and then ati tool + intel burn test to provide some good temps for the artifact testing. Still cant touch the performance of the 260M which would melt in my chassis.

 

Thats strange your ram seems to be the same as mine.
And that cpu should handle it better that mine as well.
thats crazy.

 

I just noticed your ram divider atleast according to cpu-z isnt the same as myne. You actually have the advantage since the ram is running at a lower speed for the oc.

That said one way or the other every single ram chip ever produced isnt a perfect example and doesnt perform the same as the one made before and after it. Put a bunch of chips on a stick and push it out the door who knows what you have. This level of product the ram performs at stock speeds and at the built in bus overclock levels. Need do nothing more.

I can see my ram since the bottom is off but cant see the other side with the machine on, i believe i have some jacked up samsung ram.

versus you

Timings are different, brand probably as well. Not sure how you get such a lovely divider ratio
