Very nice. Btw, does the old 775 block fit the 1155 socket without any modifications?Quote:

I used a scalpel then my nails too :D
the DangerDen block fits because my asrock mobo has combo cooler holes for older blocks :>
on my Maximus Formula 4 P67 B3 no problems at all with IVY and 2400 or more, maybe its the mobo or the IMC on your chip mateQuote:

ok thx for that info il try different memory i think first and see what happens :D
glad to help !Quote:

Timings are too tight/voltage too low. That's what I've found with my 2133MHz RAM. Had to back CL down to 10 (from 9) but was able to bump clock speed up to 2200 at least.Quote:

EDIT: See post #276 for results.
Thank You for this Post! Very interesting.
You wrote: Data collection
I use a bash script I wrote to query lm-sensors every 2 sec. The resulting data are compiled into a log file.
Is there any way, that You would share, how You collected the data?
Thank You and regards.
I sense a flash back somewhere...
So how about ambient temperature, humidity ? Your 1.288 run was hotter than 1.296Vcore ? Are the variables controlled in your test environment ? Nice approach mate and a nice way of putting things, but this will be a thorn in the eyes to those that have shared their, maybe to simple, data...
Other thing 4500mhz is still around the sweetspot for Ivy, most CPU's can do this easily around 1.25Vcore, there's close to no need to remove the IHS, if that is your targeted daily speed... it's above that IHS removal and reappliance of the TIM can be the difference between maxing out at 4600-4700Mhz before removal. And finally gaining 100 to 200MHz with lower temps/Vcore afterwards.
Final outcome will depend on test variables, amount of TIM, cooler pressure on IHS, amount/type of TIM used for core contact, ambients,... Far too many variables to provide 100% accurate data. However looking forward to your test results... my goal is to gain 100-200MHz and/or remain below throttling temps. If it's 90 or 91°C during Prime95 AVX enabled is not that important...
Last but not least : each CPU is unique... you can tell me you gained 5°C, good for you but I might have gained 10°C...
Finally i have time to try it with this subject today :D
Here we go ! ;)

No comment for behind the scenes with my camera stand xD :cool:

Tests results will coming up next, it on testing now :shakes:
Remember, I am using linux. Here is a link to the simple script. Note that you need to have lm-sensors installed and configured. Further, you have to tweak the script to match the output of your system. It can serve as a bare-bones example of what you need though.Quote:

I think we can keep this in mind when looking at the before/after table I have yet to post. In other words, small changes of say, +/- 1C are probably not real.Quote:

The board is allowing it to fluctuate based on usage; they are not discrete runs manually defining a value. The reason why there is this apparent disconnect is due to linpack. There are times where is pushes the vcore up without having a full load on the processors. This will be obvious when I show the data split out by method, either mprime or linpack.
Agreed to all of your points here. The results are not definitive from a practical stand point, but they should be from a statistically relevant point.Quote:

This is over the course of the last 2 weeks. 1 3570k w/H100 @ 4.7GHz, another 3770k w/custom water @ 4.9GHz. Results are holding constant. How many hours would you need to see to believe the results? 23C improvement in one case, 32C in the other. First with same cooling, second with improved water cooling.
It's a simple matter of physics. The stock TIM is absolute garbage. Intel's fluxless solder previously used in SB and now in SB-E chips has a thermal conductivity rating something like 20-30x higher than the stock TIM used on IB. Liquid metal compounds are the next best thing with a thermal conductivity approximately half that of the aforementioned fluxless solder, though still somewhere in the range of 10x higher than competing TIMs.
People can disbelieve all they want to, fine with me. I'll run my Ivy @ 4.9-5.0GHz 24x7 and be happy, you do what you like.
Here's a couple shots on my 3770k, first @ 4.9, second @ 5.0:

Excellent results. I don't mean to be condescending. I'm sure the diff you report is real. Think I might order a tube of Liquid Pro after seeing your results. I am only waiting because I know that AS5 has a breakin period and I wanted to give a fair comparison based on how long my stuff sat on the first time.Quote:

That I do not. I'll see what I can do, though. I'm not terribly interested in HT since it isn't useful for my purposes. I run Microsoft Flight Simulator X and do video transcoding. FSX needs only raw CPU clockspeed * IPC, performance doesn't scale with thread count and transcoding speed simply is unmatched with QuickSync @ 1.6GHz on Ivy Bridge.Quote:

Temp drops with Liquid Ultra were immediate for myself and my friend that has used it on his 3570k. No increase yet either.Quote:

No sir, I have not. I hope not to have to replace the TIM though. If I do, I'll let you know!Quote:

With that said, I am currently using Liquid Ultra + PK1 (with great results) because I like to change my waterblocks relatively frequently.
I'd use liquid ultra + indigo xtreme. No problems if lu will diffuse between IHS and core, but indigo xtreme exists only in precut forms for cpus with IHS.
I read that once Liquid Pro or Liquid Ultra set on two metal surfaces for a long period of time, say 6-9 months, the two surfaces are extremely difficult to separate. In some cases, I read about CPUs being permanently affixed to heatsinks. Can you comment? Is this true?
i like the last pic ;)Quote:

IHS it's another thing, it will get stained by these (nothing that a good polishing won't remove ).Quote:

Then I would use the best TIM between IHS and CPU block, that being sad I would avoid using any of the before mentioned LM tims just because they will stain and over time "solder" your IHS and Block together, therefore I would go for IX as a "permanent solution" or PK-1 if you intend to do some remounts.
In my system I can pull higher 50's lower 60's with a handfull of waterblocks with my 3770k at 4.8Ghz and 1.36v. Using 1.42v and 4.9Ghz will bring me to high 60's but still verry verry under control. I hope I was usefull :)
