TPU's Core i7 Overclocking and Feedback

obscenely low i guess?

yes, that is an awesome clock for voltage. If it is stable of course.

Well, I finally tore everything out of my 775 rig and install the i7 stuff in that case (with the EK Supreme). Temps are much more manageable now. @4GHz, idling in the low to mid 30's, and loads go up to the mid to upper 50's.

Only things bugging me are:

1. CPU run perfectly stable for OCCT tests, but when I reboot, the system won't POST. I've added .02v, which seems to help, but it still doesn't sound right.

2. Running the CPU @ 1.424v according to CPU-z (stock + .2v). Seems a little high for 4 GHz, don't you think?

you have a C0 or D0?

my C0 needs 1.344v load for 4GHz, it crunched a few months 24/7 like that.

Here is the link for LinX, it is a simple linpack program. It stresses CPU much m ore than Prime 95 and does it faster, Prime takes some time to build up to big stress, this has been working very well for me.

Wetbehindtheears · Jun 7, 2009

I guess it was obscenely low!

Just like t_ski it refuses to POST now... so I guess I'll just up the V till it boots - it should still be lower than normal (I hope!)

Thanks for the link Jake!

Well this UD4P seems easier to overclock than my old DFI did and does so with a little less voltage, although I still need to get to grips with some of the BIOS...... I cant compete with some of these D0 chips but 4gig with HT enabled (although it is enabled it still does not show it in CPU-Z but it is in BIOS and shows as 8 threads in device Manager?) on 1.26V full load with idles at 38C and after half an hour of OCCT I hit 58C on air....... need to push further now!

Chicken Patty · Jun 7, 2009

very good tatty, that is one nice C0 you got there :toast:

Wetbehindtheears · Jun 7, 2009

Observations so far:

Whatever voltage I set in BIOS is not necessarily the voltage shown in CPU-Z ( I was watching during a LinX run and it did vary and bore NO relation to what was set in BIOS!)

x21 multiplier seems to appear by magic - I can't set it to x21 myself! (I'm working on speeds in BIOS with x20 but CPU decides I want x21! Is this anything to do with lower core V?)

There are far 2 many settings that I can play (ie kill!) my CPU with!

I've started again from scratch (stock) will post my best result later...

Thrackan · Jun 7, 2009

Voltage set to vCore should appear in CPU-Z. Might be a little difference due to vDrop.
Difference between idle and load voltages can be dealt with by enabling load line balancing in BIOS (if your mobo has it)

For the record:
vDrop = diff between BIOS volts and reported (actual) volts in Windows by ie CPU-Z
vDroop = diff between idle and load voltages

x21 is Turbo mode, turn it off under advanced CPU features to see a constant x20

Jakethesnake011 · Jun 8, 2009

I was able to stop my multiplier problem for now. I am able to have a constant x21 when idle and gaming, but when stressing it still jumps down to x20 I think of heat and it automatically idles. I hear that if overclock is over 4.0 or close to it and the voltage Vcore is 1.35 or higher the x21 will go to x20 when under load, anyone confirm? But I used this guy's multiboost program unclewebb from i4memory.com, and XS works well and gets the job done, in case anyone else has the problem here is link.

Urukland · Jun 8, 2009

If you have multiplier drops in load, you must search in your bios an option to disable TDP protection. In my DFI t3he8 is Set VR current limit max.

mudkip, I think I have your low-voltage OC beat:

FYI - That's the display off my Logitech G15

mlee49 · Jun 8, 2009

T-Ski, nice voltage, nice temps! :toast:

Anyone getting really good timings with their 24/7 overclock? Here's mine:

2:10 = 1333 @ 7/7/7/28

I want to run them tighter but they may need 1.7V+ to get much more. I'm trying to remember what by fastest WPrime run timings were, but I cant recall of the top of my head.

t_ski · Jun 8, 2009

Here's mine:

Chicken Patty · Jun 8, 2009

what multi you guys using on the CPU?

heres mine at 3.8 GHz 182*20

mlee49 · Jun 8, 2009

Holy memory GB batman. 12GB! Looks like I can tighten down mine a bit.

LOL. 0.0v. Might as well unplug the PSU. :laugh:

Jakethesnake011 · Jun 8, 2009

here is my timings for the RAM I have the OCZ Platinum 1866 CL9 stick, and they are rated for 9-9-9-24, so far I have been able to run them as shown and they run great. I wanted to see if I could get them like Binge's Hyper's to 6-7-6-15 or so, that would be nice, since I can not go much higher with memory divider or it will shoot my RAM up to 1900 MHz and I would rather have tighter timings at the moment.

Thrackan · Jun 8, 2009

I think I'm going to lay off the OCing for a little while.
My little adventure blowing up my motherboard kinda scared me a little. Will keep an eye out here though...

With Turbo enabled the multi will drop to 20x once thermal temps have hit 60C I beleive, I did read it somewhere..... and there is no way of disabling that.

Thrackan · Jun 8, 2009

I never saw that, but then again, I disabled those temp threshold options in BIOS...

You can disable everything in BIOS, the multi will still be lost at temps above 60C I beleive.

Thrackan · Jun 8, 2009

As you can see here, temps are over 60 and still x21 multi...

Binge · Jun 8, 2009

Alright folks I've returned home and I just want to say I learned a ton, but before any long stuff I wanted to say I'm really glad to be back and really really glad to see some tight ram.

@Tatty: Some motherboards have a way of sending a signal to the CPU that there is no temp over the limit for turbo activation. This was first introduced by Gigabyte and then later adopted by just about every board manufacturer. Trust me it makes no difference in temps. This past weekend SV and I had i7s doing 4.66GHz(turbo on) on air/phase/DICE without any real difference in wprime, pi runs... nothin.

@Everyone else: Don't ever stop learning and searching and digging into this chipset. It's complicated as hell, and it doesn't seem to mind a bunch of heat for short bursts of overclocking.

Makes sense since I run a Gigabyte board...
