Overclocking

Overclocking Dell Optiplex 320 – OEM Computer – P4 Prescott @ 3450MHz

I’ve been using this Dell Optiplex for awhile now. It acts as my spare rig to use while I’m benching my other one, and I also use it for word processing and other simple tasks.

I was just looking at the CPU-Z screen out of curiosity today, when I realized that an overclock on this machine is potentially possible.

3DMark06 – 1090T On Stock Cooling

Thought my board died tonight. Eventually got it back up and running and chew* inspired me to do a 3DMark06 run on the stock cooler. Here it is:

|Deep Freeze| – |LN2Cooling.com Evaporator| – |Phenom II X6 1090T @ 5.625GHz|

I got in touch with a friend and he agreed to let me take one of his cooling pots for a spin. Aaron Schradin of LN2Cooling.com has lent me an excellent pot to play around with and review for all of you guys. This pot is usually meant for the purpose of running under LN2 and LHe4. This is seen in the many AMD world record breaking overclocking attempts, which can all be seen over at amdblackops.com. However I will be playing around with the dry ice performance of this pot, which has mostly been overlooked until now.

Canadian Winter – Winter Air Overclocking W/ Phenom II X4 955 C3

Back for my most recent blog post after a prolonged break from the OC scene, I bring to you some fun winter air testing. I used the same setup as previously. This mainly consists of my trusty Phenom II 955 X4 BE, Gigabyte MA790FXT-UD5P, and Ballistix D9GTS 2GB DDR3 set.

Ahh, the familiar feeling of Canadian winter. A dreaded feeling for most, but hey, I’m an overclocker……and I like cold weather for one purpose….

|Slappa’s Slushbox| – |Phenom II X6 1090T Overclocked In Ice|

Long story short. Today I got pretty bored. I’ve been wanting to put my 1090T under dry ice for quite some time now. However, my bench partner has been busy with work so I could not obtain the dry ice pot.

So I was thinking of ways I could cool down my processor, in order to play around with my new 6 core. Since I own a Corsair H50 AIO Watercooling kit, I decided to have some fun.

I hung the radiator in an old lunch cooler and filled it to the brim with ice. I also threw a bit of water in for more cooling surface area. I figured this could get my processor 5°C or below. I was right. Yes, the slushbox idea is not a brand new innovative one, but I wanted to try my chip under something else then regular cooling for now.

My first dry ice run on the Phenom II X6 1090T.


|Second Frost| – |Overclocking AMD Phenom II X6 1090T Under Dry Ice| 5.568GHz

Hey guys, here is my most recent run. As you can see, I improved my results from my last run slightly. I also took a lot of video of the setup and of how I do my sessions. This is to give you an idea of what it is like to benchmark on dry ice.


2000MHz Memory On AMD W/ Phenom II X6 1090T & 890FXA-UD5 [Part 1,2,3,4]

As you may know, the release of the new AMD Phenom II X6 chips, combined with their new 890FX chipset platforms bring a lot of changes to the table. Due to changes in chip electronics, they have massive overclocking headroom, not just for the cores but also for the IMC (northbridge frequency). The 890FX chipset features the ability to now push ram speeds ahead of the previous AM3 maximum (which was around 1600-1800MHz). New boards support up to 2000MHz. This is a victory for many high performance ram users, now able to run their ram at their rated specs. This is also a benefit to overclockers, who can push budget ram above and beyond their stock specifications.

Bassplayer’s SuperPi Competition @ overclock.net

Hey guys, here are my entries for this competition. They are done on my slushbox cooling as seen in my previous blogs:

OCN Small Time OCing Competition – 1st Place In AMD X4 Air Class

I recently won a small time benchmarking competition on OCN. Had tonnes of fun. You can check out the competition thread here.

Phenomenal Dry Ice Run[Video]

So yesterday Slappa and I did a bunch of dice runs on three Phenom II’s: the Phenom II 940, 955 and an Phenom II AM3 ES. We got some really good results with all three.

4.2GHz Stable 1090T – Air Cooling Venomous X-RT

Looks like the new Venomous X-RT is doing a good job. Heres 2 hours of prime.

Dry Ice & Phenom II X2 555 – 5648MHz

Did a live stream of my 555 dry ice run the other night. Not very eventful, however I did manage to pull out once decent core clock. This particular core was better than my best 1090T core which maxed out at around 5579 valid. Enjoy the MHz.

2000MHz Memory On AMD W/ Phenom II X6 1090T & 890FXA-UD5 *Continued*

I did some further testing at 2000MHz ram speeds. I discovered that my settings for my 1m Super Pi run were not entirely stable for 32m testing. So I revised a few sub-timings and was successfully able to run 32m. This involved loosening the tRC and tRAS. Keep in mind that this run was done for stability, not to break 32m time records.

2000MHz Memory On AMD W/ Phenom II X6 1090T & 890FXA-UD5 *Part 3*

I managed to hit another 32m stable result, and was able to lower the tRAS back to 15. 32m stable means that this ram speed is stable for almost any benchmark and most daily computing. However it is not 100% until it has passed at least 3 hours of blend on Prime 95. This is to ensure the ram and NB are fully stressed and simulate the maximum stress these subsystems will ever recieve.

2000MHz 7-10-6-15 w/ Phenom II & 890FX (Prime Stable)

Hey guys, I finally reached my goal. I got 2000MHz on my ram stable in Prime 95 (finally).

Phenom II X2 555 Cold Air Fun

This 555 that I have here in my bench, has an extremely high VID (1.425V) which is normally terrible for a CPU meaning it will not overclock well. This chip did quite the opposite. Not as good as some 555′s, it still managed to unlock and overclock successfully. Here is what I did last night with it at around -7C to -8C.

-10C Fun W/ 1090T & H50

Fairly Average chip. Best core was core #1 so i ran all my stuff on that. Ram is mushkin ridgebacks. Rig is hanging out my window with H50 cooler.

LN2 Is Here FINALLY! – Slappa & Addies At -196C

Video
As a benchmarker, the biggest milestone you will come across is your first plunge below -100C. Liquid Nitrogen is -196C by nature, and to utilize this exotic cooling material, you need a fantastic evaporator, or more commonly known as a pot. Much like dry ice, cooling the processor down this cold will decrease impedance that opposes electron flow. This allows for a more efficient circuit, promoting greater stability and overclocking headroom.
