Intel Pentium G3258 Performance and Owners Club NOW with GTX 970 - Page 162

post #1611 of 4581
Hello

I would share my current setup that many people will be able to use without having good O/C batch (mine is bad batch).

This is using adaptive voltage that lets the procesor "cooldown" , a good air or basic water setup is recommended, but if you put a good air system with lots of air inputs will be more o less the same.

First of all you have to delid the processor and apply for example Collaborative labs liquid pro between die and ihs and then ihs to water or air block (optional) , in order to get good temperatues otherwise will be impossible, at 70-80º processor needs atleast 0.05v more at same setup to be stable, but this adds more heat...

I getting stable 4.7GHZ and 4.4 cache without put big big voltage and tested days trying different settings. For testing I used the prime95 at same time of intel burn test in order to get the maximum possible power drain and heat.

Vin (procesor input voltage): 2.1v
Vcore adaptive max voltage: 1.32v
Vcore offset: 0.08v

This means that in idle it will run at 800mhz at 0.08+0.82=0.89v , when it scales , scales 0.08 over the stock voltages until the max that is 1.32+0.08v = 1.4v

Cache (uncache)
Vcache adaptive max : 1.32v
Vcache offset : 0.02v

This means that at max it will run at 1.34v

This setup is prime95+intel burn test stable, plus played several games without problems, the procesor runs at max 58-60ºC at max speed with 25º ambient temperature on Corsair H90 water push and pull setup.

I noticed that between 65-70º the procesor needs 0.02-0.03v more in order to be stable.

1.4v in this procesor with cooldowns of frecuency and voltage scaling(for 24h/7) is not high and the temperatures goes from 33º to 60º when it scales, so it is nice.

In the past I had a i5 4570K @ 4.0GHZ running almost 87º on same setup and in World of tanks it was running @90fps the intel G3258 runs 100-120, nice ehhh! Because this game is not optimized for multicore.

As final words I recommend to add more fields to the table for in case of FIXED voltage overclock or ADAPTIVE voltage overclock.

Pentium's IMC is specced at 1333. Not 1600. That's why.
See on ark.intel: http://ark.intel.com/products/82723/Intel-Pentium-Processor-G3258-3M-Cache-3_20-GHz
As far as I remember, it was only single ranked RAM that was really really bad at 1333. My kit is 2r.

Same with using an uncore speed of 3200 vs. 4200. Comparing stock vs. OC.

I asked for those benchmarks coz from my own testing with my Palit GTX 750 Ti StormX Dual, there is no difference between 4.0 GHz and 4.3 GHz. There is only a small improvement going from 3.2 GHz to 4.0 GHz. I used a legit copy of Metro: Last Light for benchmarking (built-in benchmark tool)

My G3258 chip is limited to 4.3 GHz @ 1.325 Vcore that is why I can't test CPU core speeds up to 4.5 GHz. Based on my results, I just decided to run it at 4.2 GHz @ 1.275 Vcore

By the way, for the single R9 290, are the results also the average of 3 runs ?

4.2 or 4.3 should be enough for everyday use, at least for Grid 2 my graph should show that. For the single card runs, I did not run every setting 3 times. I did a couple runs twice to double check, but seeing the average fps rise ever so slightly should be indicative of a GPU limit.

Hello everyone!

I'm new to overclock.net and this is my first post, I'm having trouble overclocking my G3258 chip and am hoping someone an shed some light on this for me by answering a few questions.

Here are my current rig specs, I just put this rig together less than a week ago and everything has ran phenomenally stock. It's ran most of the games I've thrown at it great stock, I just wanna go fast wink.gif.

G3258 CPU
Corsair Hydro Series H60 Cooler '2013 edition'
MSI H81M-P33
2GB Mushkin PC1333 CL9 ram
ASUS GTX465
1TB WD Blue Caviar HDD.
Rocketfish 550W 80plus PSU 'Click Here.'


Here is where my questions begins. I picked up this cpu/mobo combo after reading a couple of articles the last week regarding how well the overclocking numbers were, specifically the Tom's Hardware article that used this exact same motherboard to reach 4.6ghz. I however am not having the best of luck even coming close to this number. Since this motherboard isn't technically supposed to overclock this chip the instructions on how to do so are very vague and confusing to say the least. I havent found a good guide explaining how to overclock with this board. I have however figured out how to change the clocks and voltages etc.

Leaving all of my OC options on auto in the BIOS and just changing the core clock to 40 and Vcore to 1.250 I can run rock stable @ 4ghz. I left AIDA64 running the fpu stress test for 7 hours and the hottest it got was 50c with an idle of 34c and no failures, this is the minimum voltage I can use though anything lower will become unstable. This voltage seems very high to me though for just a 4ghz OC compared to others I've seen in this thread, is there something I can do to lower the core voltage but keep stability? It should be noted the temps between core 1 & 2 vary between 7-10c during stress testing, but the overall temp is still considerably low. Would turning off EIST and C-State allow me to set a lower vcore and still remain stable? What about adjusting VCCIN or Ringclock/voltage? What about using fixed/override options for clock speeds and voltages?

The best I've gotten was 4.2GHZ @ 1.320VCore and a VCCIN of 1.8v, EIST and C-STATE disabled everything else set to auto. These voltages look very poor to me and make me think I got a dud processor.

All hope is not lost though, I am checking out an ASUS Z97-A motherboard at a local retailer that I can get for a song and was wondering, will a higher quality mobo with a Z97 chipset and much higher quality voltage setup allow for a better overclock with less voltage being consumed? Could it jut be the H81M board I'm using giving me poor OC ability? Or does board not matter and I lost the processor lottery? Should I buy another processor and give this board another try before buying a new mobo and giving it another go with the same processor?

If anyone can shed light on my questions it would be greatly appreciated.

p.s. I have 8gb '2x4g' of PC1600 ram on the way. This rig was put together for a very low price as an upgrade path so I'm not worried about upgrading anything.

welcome, check out the haswell oc guide in the intel cpu forum, the x264 software in the guide is very good for finding your oc, its suprisingly hard to pass. for the oc basically leave everything at stock and adjust vcore and vrin only and find your highest multiplier. there have been a few cases of ppl with low oc, so its entirely possible ypu have a bad oc chip, what stock voltage does it have? would be interesting to see if the new mb helps, your msi h81 probably has a 3 phase vrm while the asus has 4 iirc, but generally the lottery is with the cpu.

Thanks, it does have a 4 phase vrm:'Click Here' I'd be picking it up for 110 so it might be a bit more expensive than the board/chip ratio but I seriously planned on lighting a fire under this chips butt as long as I could, I haven't overclocked since the Socket A days so I was hoping to relive some glory with this chip but it's turning out to be a bummer frown.gif. incoming screenshot of stock hwinfo in a min.

I noticed core voltage always displays at 0.144 no matter what software use, I've come to the conclusion this happens with all H81M-P33 boards.

raising input voltsge can help lower vcore also make sure cache is running at stock until the core is dialed in.

mm 1.09 stock vid is above average, my chip is 1.056 and it does 46x with 1.34/1.92 vcore/vrin x264 stable on the msi z97 pcmate, which is also 3 true phase split to 6 phase. imo it looks like a bad oc chip.

sometimes the vid can be missleading though. Lower is still generally better but if the cpu doesnt scale well past a lower multi it wont matter what the vid is.

Im in the same boat as you frown.gif

4.5 needs 1.3 on the core, and then 4.8 needs 1.5 on the core, with 2.3 vrin.

Im also new to this haswell chip. So I may be doing something wrong. I have only adjusted clock ratio to 48, vrin to 2.3 and vcore to 1.5. I disabled cstates as well and it seems to have helped with stability
