Intel Pentium G3258 Performance and Owners Club NOW with GTX 970 - Page 179

post #1781 of 4581
@ IOWA

I'm not just comfortable with that Vcore so I turned down to 4.2 GHz @ 1.275 Vcore

Even with my previous Core i5 750 and Core i3 530, my Vcore for daily usage is less than 1.3 Vcore

Revalidated it, http://valid.canardpc.com/y46p53 had some cpuz problems!

5.2GHz air cooled guys!

over 1.7V sad-smiley-002.gif

I think it may be a dud as well. I'm 1.35 volts to hold 4.5GHz and I don't consider it reliable. It's not really a temp issue, any time mine blue screens the temps don't clear 70.

Your chip actually doesn't sound too bad to me, the reason I call this a dud chip is because I could only reach a stable multiplier of x42 and cache of x36 with a voltage of 1.35-1.375. I would have needed over 1.4v vcore just to stay stable at x44-45, definitely a bad overclocker.

Lapping is meant to create two flatter surfaces to leave less gap as compared to concave/convex IHS from the factory. In the end you can make it as shiny as you want but if it is still an uneven surface, then the only thing you did was make it shiny and not help in the effort to drop temps...

Thanks for the info, I didn't know the IHS had a concave design and hence why the edges of the chip exposed a little copper.I was planning on soaking the IHS in a glass of 99% iso for a few minutes and then giving it a good rub down with a sterile cotton cloth to pull any remnants of buffing compound off of the IHS and make sure it's clean before using it on the new chip, I also did it on a flat surface to make sure the surface was going o be level. I can also give it a second go on my good chip's IHS as the first one was simply a test run at it, I could definitely improve on it with the other IHS.

Here's is a pic of the finished product.

Hi,

I'm having some issues with my G3258 and was hoping I could get some pointers as to what I'm doing wrong, or if I just got a bad chip. I'm new to overclocking, except for some heroic attempts on my old E8400 a few years ago, so I'm still hoping the problem is on my end biggrin.gif

My MB is MSI z97 g43 with a CM Hyper TX3 evo cooler.
Following the guide to OC haswell chips I enabled advanced mode in bios, locked the ring ratio at 32, set ram to ddr3-1600 MHz, and started upping the CPU ratio. Im running with vcore at 1.295, since I'm after the highest possible 24/7 settings, but have tried going to 1.3 as well, but I just cant seem to get it stable even at 4Ghz. After about half an hour playing WoW it will reboot, refering to bad OC settings. This also happened using OC Genie.

The settings shown below is the highest I've been able to go over a few hours, and even now HWMonitor shows max temps at 76C sometime during my last 2 hr gamingsession which I think is a bit on the high end. As im writing this temps are ~43C. I have refit the cpu cooler just in case i botched it the first time, but it hasnt made any difference

I currently dont have any issues running WoW smoothly (I settle with 30 fps steady in raids smile.gif), but I cant help being a bit jealous of other posters here reaching higher clocks, seemingly without any problems.

First thing I notice off the bat is you haven't raised your VCCIN, it's a good rule of thumb that VCCIN should always be .500 more than vcore. Looking at the screenshot you should raise your vccin a bit and see if that helps stability. Also 76c is pretty high for just gaming temps with that overclock. With a 4.5ghz overclock and 42ring on my rig I don't exceed temps of above 50c gaming on Alan Wake, Endless Legend etc. my cpu is underwater though. You can always do the quick and dirty method and set VCCIN to 1.900 and vcore to 1.300, leave ring locked at x32 and ring voltage at stock for now. then select your target multiplier and see if it will boot up, if so run a stress test for stability making sure to keep an eye on themps, if all goes well begin to lower voltage in increments of .010 until it becomes unstable again then raise it up to the previous number. after that do the same with VCCIN until you're zoned in. THEN move onto overclocking the ring.

p.s. leaving your power settings in WIndows on balanced will affect overclock stability, set it to high performance.

__________________________________________________________________________


So I spent a good 5 hours today dialing in my good chip to get some solid numbers for temps after delidding. Her are my results after 2 passes of intel burn test and one pass of x264.

CPU Multiplier = x47
Ring multiplier = x44
VCCIN = 1.900
Vcore = 1.375
Vring = 1.250
Idle Temp = 35c
Intel Burn Test Temp = 80c

With these settings running Intels Burn test I reached temps of a solid 80c, temps on x264 were lower. Gaming on these settings I saw temps in the mid 50c range at the highest. trying x48 at 1.4vcore boots up but is a bit unstable so I toned it back to 4.7, what's 100mhz when you already have a 47% increase in performance wink.gif.

I wanted to validate it but this board doesn't display my vcore properly in cpuz. If you guys want to see screenshots let me know.

Question

I purchased 2x4GB PC1600 Mushkin Blackline Enhanced ram, I understand the g3258 only supports up to pc1333 and I can see it's been toned down in cpuz to 666.5mhz, so it's running at pc1333. The MSI H81M-P33 board I'm using however supports PC1600, should I even bother overclocking the memory to it's rated pc1600 to see if I gain any performance? Will it work since the cpu only supports pc1333?

Totally, @1.3V vcore pump vccin up to 2.0V (0.7delta) but it will not do too much; set LLC to extreme or 100%, set the cooler fan at a higher speed. You can also try to rise vcore to 1.32V.
remember to disable spread spectrum, disable all energy saving options, windows must be in performance mode (power options--> performance mode).

Try to reinstall correctly the cooler if temps rise too much.

I'm going to give up trying to OC this thing on a H81 motherboard...

I got a new processor and a new GA-H81M-HD3, i even got a beta bios from gigabyte where you can set the vcore higher than 1.2v and i still can't get this thing to work.

This is just retarded, even if i ONLY increase the VCore more than the default 1.1v Windows wont boot at all... the loading screen with the logo shows and the it just reboots...

I can OC it to 4.4GHz, set the VCore to like 1.4v and VRIN to 1.9v, i can even boot into a live Linux but NOT Windows... ?????? and it can't be because of stability issues because of what i said before (default multiplier and only a 0.1v increase to the Vcore will make Windows unbootable).

Spend the extra 30 or 40 on the board I have, Z97-SLI. Decent board for a $100, 2 8x SLI/Crossfire and will work nicely if you upgrade to an i5/i7.

I don't think there's a point to pushing vring that high, just to maintain the higher ring multiplier

My chip can use 1.15v on ring and do 42x ring.. 44x ring requires 1.25 like yours..


The reason I think this trade is bad, is because the cache increase gives you ~0 % performance boost.. It also doesn't affect Memory overclock..


You're better off just saving some heat on cache, and buy a pair of 2400mhz ram.. for m0re snappiness instead
