i7 3820 - 4820 Overclock Club - Page 637

post #6361 of 6510
Intel made L1 caches MUCH faster in haswell. Thus a lot of stuff like emulation become significantly faster. They also made mistake. Both CPUs have HT.

BTW 6600K is exactly the same as 4820K with HT disabled. (Faster per core, but smaller cache. So it evens out. 55GB/s RAM speed on Ivy-E can be made by overclocking DDR4 RAM in dual channel. I ran default 1600MHz at 1.35V DDR3, and I use DDR4 at 1.2 V. The resulting transfer speed is the same.)

so what is the point of your comment? Who is faster now?

I'm saying HEDP are like comfy cars with wooden decorations. They sit well on the road and can last ages.

Faster? Now it's about MORE CORES. (Actually KB-X would be probably fastest and would be on new HEDP. But it would be four cores only...)

4 vs 8. I think 8 is still better than 4. Especially when it comes to oc values...thumb.gif

I'm no longer a member of this group.
I recently did a complete system overhaul and sold my old 3820 in the process.

Upgraded to Core i7 6800K
16GB (4x4GB) DDR4
Asus X99-A
Gainward GTX 1070 8GB

Overall, very happy with the upgrade.

That's huge boost! I believe your gtx1070 has Samsung memory too. All of the AIB cards changed to micron from Samsung, and instead of hitting 9Ghz plus, some have issues running even default.

The 6600K is out pacing the older i7's even with only 4 threads it's giving CPU's like 3770K a easy run for its money even with 8 threads. I run mine at 4.91Ghz

I'm still partial to my X79 platforms though.

Nothing can compare to a 3970X running at 5Ghz for the money ,$160 on eBay! That's a huge value.

Hi
I posted this over in the Asus MB forum as well and then noticed this one. Stil finding my way around so I hope I can get some advice regarding my 4820 here please.

Hello, a new member here and am slowly going through the site trying to get caught up. A monumental task but have found a couple of niches that I fit in, this thread being one. As a beginner but enthusiastic clocker I would appreciate any insight or suggestions that might help me better understand and get the best or most out of my 3 year old rig.

Asus x79 Deluxe
i7 4820k @3.7
16GB Dominator Platinum 1866 CL9
EVGA GTX1080 FTW ACX3.0
Corsair H60 Hydro
Corsair AX760 Platinum
EVO 850 Pro 256GB
WD Black 500Gb
WD Blue 500Gb
NZXT 410 Phantom

Right, now the issue.
At the moment I have the UEFI set to 'Performance'. This results in a reported Turbo of 4.3. And there is no stability issues. Now, I have just run Prime for about 15 minutes. The reported CPU-Z Core speed was 4.199 and peak Vcore of 0.608. Temps measured by Real Temp did not exceed 70 C.

The Question.
Should I go manual and see if increasing Vcore and multiplier will get me to 4.5 and beyond? It seems to me I have a lot of headroom left in Vcore and the temps are still under 70C. I should say that one day while clumsily playing around in bios I bumped the RAM target to 2133 which resulted in the CPU going to Turbo 4.5, however when I looked in Task Manager Performance on the Memory tab I saw that one of my modules was not registering. So I think I did something ass backwards there. I would like to try and push the memory to 2133 as well if possible.

I would appreciate any suggestions and recommendations. (I am in the market for a 4930k or 4960x realizing that 6 core CPU would probably be better)
Thanks

Add me please. Im loving this chip! already at 4.35 just with Multi, than moving onto the raising the BCLK and mix things up to get around 4.6+ which im confident considering temps and I haven't yet began reducing voltages...(By the way CPU-Z shows my VCORE @ 1.44 ish i think. I don't go off software based monitoring/overclocking. I use my Multi Meter / Voltmeter for more direct precise info of which my Voltage reports @ only 1.388V)
