Significance of cache size? Do higher clocks allow higher overclocks? HT = More Heat? - Page 2

post #11 of 19
Probably because most of the people with 2600k's keep HT turned on to show that their chips can perform at full potential at 5 ghz. If you look at some of the XS forums, back when the 920 d0's appeared, when people were posting screenshots of 4 ghz with HT off, others were like "that's not fair; be a man and show what the cpu's can do and throw on HT."

Most of the people who turn HT off when flaunting their clocks are the ones going for 5.4 ghz+.

If those people had HT on, in the chart you posted above, then you could easily take off 0.025v off their voltages, and then have a 2500k with 2 mb more cache, and you're right in the ball game with the voltage results.

But yeah I've seen some 2500k's that refused to go higher than 44x multiplier with PLL override disabled....

Here's one of mine, done a few weeks ago:
Quick bench cuz I hate running prime and degrading my chip. I only ran it for one full loop (17 minutes) until the temps reached 84C (they shot up FAST after the first loop (which takes 15 minutes) was finished, so I ended the test. Don't want a degrading cpu...



Look at the vcore on that.
If I had HT disabled, I might be at 1.38v.
Yeah if I were using SP1 (W7 is on a dual boot) and AVX+Linpack, I would probably need a small vcore bump. Then again, since I have a "leaky" cpu (low VID/runs hot/responds well to voltage), temps might be too hot for comfort with my Ven X...

Another thing is that some people post their BIOS voltages, instead of their max load voltages, so you never know if the voltages are at load, are in BIOS and they're using LLC2 to raise vcore at load, or in BIOS and their load voltages are even lower...

I was set on the i7-2600k, until I read that HT has the processor run 10 degrees hotter than it would with HT off, this was an automatic turn off for me, as I would imagine OC-ing the i7 would be a more difficult task than the i5 (to reach the godly 5Ghz). But this rose the question of cache size and default higher clocks that the i7 has over the i5..

So my main question is really how would i5-2500k compare to the i7-2600k w/ HT off? more specifically, when attempting to OC.

I ask this as I'm the type of user that wouldn't want to go into the bios every time I require HT, it'll be either on, or off. To be honest I'm not entirely sure that I do.. apart from heavy gaming, I mainly use the entire spectrum of the Adobe Creative Suite CS5 (for web design, flash, some audio fun), though not very extensively.
2500k will be great. If you are gonna take of HT then you are basically getting 33% more cache from $100. I dont think the performance is so much higher that it can be justified. And adobe suite wont be significantly faster. Grab a better gpu or an ssd or more memory.

I'm really more concerned of how the 2500k & 2600k (HT off or on) OC, and how the heat levels compare as I am determined to hit 5Ghz with a 1.38-1.42v, so I can have it run 24/7.

The impressions I'm getting from both Falkentyne and Chickenman is that the 2600k is more up to said task.

While saving profiles is an option to me to run HT on or off, i don't really care to have to reboot -> bios just to make use of the HT. So I'm gonna keep HT on and configure everything to reasonable setting.

I don't know if your going air or water cooling, but i reseated my cooler yesterday and temps dropped 2'c, finally installed video drivers last night as well and out of curiousity ran P95 for 20mins and temps dropped another 2'c, making my highest temp now 81'c

currently at x48@1.392 load, idle is .9xxx (4hr P95)

While i do want to see what my chip can do, i never intended to run it at max 24/7 anyways. I'm getting the impression from my chip that it could possible be stable at higher clocks (batch#L044A892) but on air cool the temps are pretty high (earlier testing prior to reseat and driver install). I'm gonna pop my side panel off today for a quick P95 20min run and see what temps look like, this might give me some indication as to whether more airflow is needed.

Oh I'm going water cooling, most likely the H60, should be able to handle the OC of SB processors just fine I would assume.

Running it 24/7 @ 5Ghz is my intention at hopefully 1.38-1.42v, thus the point of this thread: if the i7-2600k was any difference in OC abilities when HT is turned off, which it seems it is.

Hey Falkentyne, West Co. used to be my stomping grounds! All up in Azusa, Glendora, that part of the East 210. Cool to see someone local! Cheers!

if your doing graphic and web design with audio editing i would suggest going for the bigger cache. it will help it load stuff a bit faster and process info a decent amount better. i went from a phenom to a phenom 2 with the bigger cache, and even at the same clock speeds i notice a huge difference when i am designing stuff in coral, or working with enroute, or other programs for work. gaming seems to be about the same though.

I moved up to SF 2 months ago. Pretty sweet up here, but I miss SoCal too.
