Haswell Overclocking Guide [With Statistics] - Page 618

post #6171 of 19578
Nice RAM.. I'd drop it to 1T though and see how low I can get tRFC, for me it's ~120 but it depends on memory and you might get it lower. You can of course start playing with more settings but when I tried it only brought me another 3 points in Cinebench so .. waste of time by any definition (unless you're trying to beat people at HWBot).

Is batch number L314B506 a good 4770K ?

Just buyed this one with MSI GD65 Gaming Z87 and H110 140 mm W cooler.

Once every thing is mounted in my Corsair obsidian 750D I will share my results.

Especially since I was working on 4.4 and eventually gave up on that. Hence why I haven't had anything to chart yet.

But the question was, is any part of that real bench synthetic?

You'll know for sure once you start overclocking it.... thumb.gif Haswell isn't like the older CPU's - where the quality was dependent on the batch that it came from. If you check out various sites on the 'net, you'll see this....So far, the most common indicator of a good overclocking CPU is what the default vcore is at - the lower the initial vcore, the higher the OC....Looking forward to seeing some results, happy overclocking! cheers.gif

Yeah I got that LOL. So basically it looks like it's NOT synthetic smile.gif I ran the bench.. here's the result:



I'll try the stress another time smile.gif

Your goal is to get close to stability, and then to tweak. 124? If your uncore is down as it's supposed to (manual uncore 100mhz below stock so no turbo) and ring is at a good setting (like 1.2v) then it's obviously vcore - you can throw +0.02vcore, if you get no sign of issues whatsoever for the next few days, drop it by half of that if you want.

Ya know the funny thing? I was running benches, I was multi-tasking.. (no games yet) and basically a lot more load on my system than last night and haven't crashed yet. And I haven't changed a thing in BIOS! This is a weird ass CPU!

I'm completely new to overclocking and I had a question.

Asus Z87 Pro and i5 4670k. I'm only messing with multiplier, voltage, and cache. Cache is set to 38 and hasn't been adjusted.

So I got to 4.6 at 1.263 voltage. I think it could go slightly lower but I haven't had time to test. But as is, I think that's a good result, no? But my concern is temp. After 16 hours of prime95, temps ran in the 80s Celsius, peaking at 86c.

Is that too high? Seems high to me. Idles at 24-29c. It's a barebones system ATM so I haven't been able to see game loads etc.

Of I take it down to 4.4 I can go 1.13 volts (might be able to go lower) and prime95 will peak at 63c. I'm thinking that's probably the better option?

Cooler is a D14 with 2500rpm TY 143s so I can't improve much there.

it seems you have RealBench v2..... I have 1.05. Where did you get yours from?

no that's not "too" high. But I wouldn't allow it to go any higher if you plan on having the pc for awhile. Looks like you have a good chip too. im jealous. Mine takes 1.45v to do 24hr of prime at 4.6 /sigh. My first one was better but I dropped it lol.

anyhow, so you know, your temperature is going to go up when/if you oc the uncore as well as the ram... also accompanying voltages due to intels infinite wisdom tongue.gif

This will push you into that territory I suggested you avoid. This leaves you with a few options. Lower your OC (4.4 is still a fast arsse chip) or get better cooling/delid your chip.

To give you comparision, my awful chip that takes 1.45v to do 4.6 stable does so without passing 75c (of course its delidded, ran naked, and watercooled)

have fun!
