Seems these new denebs have been surpassing the thubans quite a bit lately when looking at individual cores.
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.
Core #3
890FXA-UD5
Corsair H50 chilled by cold air

Instructions
-Use the stock AMD cooler provided with your X6/X4/X2 processor
-Use Any Black Edition CPU (955,965,1090T,1100T,555, etc)
-If using a dual, it must be unlocked
-Boot with 1.475Vcore in the BIOS
-HT Ref set to 250
-Everything else stock so that nothing interferes
-Boot into OS (Good to use a stripped OS with less interference)
-Use AMD Overdrive 3.2.1 – DO NOT UPDATE TO 3.2.3
-Start with core #0 and see how many multi jumps it can make before it crashes. IE: made it to 4500MHz but crashed trying to go to 4625MHz, it is then considered 4500MHz.
-Work your way up until all the cores have been done
-Post your results for all cores + Batch + Chip VID + OS
-Screenshots not required, but helpful. No sense in lying in this thread anywaysThis may be a lot to ask of you guys. However, this will be very interesting to see how many chips have combinations of good cores and bad cores and which batches are the most balanced and overclocked the best.
CPU Batch is on the IHS of the CPU, no other way to check. VID can be checked by looking at the stock voltage set in the BIOS on auto, but make sure C1E, CnQ and all that is disabled.
I’ll start with mine for an example:
Slappa – 1090T 1.3250VID – Batch 1018EPAW – Windows XP 32 Bit
Core #0 – 4500MHz
Core #1 – 4625MHz
Core #2 – 4500MHz
Core #3 – 4375MHz
Core #4 – 4500MHz
Core #5 – 4375MHzSo as you can see my core #1 is the best. This will show me what core to use when benching for superpi or other single threaded apps. This also tells me that I should use this core to suicide. Remember that when doing a 6 core overclock, the bad cores will hold your chip back. So cores #3 and #5 hold me back on my chip.
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.
Top H2O scores for 1m and 32m on the bot for this chip
Here is my post taken from this hilarious OCN Thread
-I’ve baked 3 graphics cards
-Killed a x1300 hard modding it
-Lots of pencil modding. Did my 5870 tonight:
-I have delidded around 3 Phenom II’s, one was an ES, 3 were 740 X3′s. I killed all except for one 740 either by crushing the core after delidding, or killing the chips in the delidding process:
-Put my finger in a fan today and sustained a large cut-Spilled my melted slushbox cooling water (which had salt for lower tempertures) on my internet modem. I heard a sizzling and it would not power on. Salt water is super conductive. But eventually I dried the thing out and it still works fine to this day.
-I cooled my beers down with dry ice.
-I flip over cans of dust off and spray the super cold liquid (-50C) to cool down my cpu or graphics a bit during air benching
-I put my PC fully out my window fully exposed and caseless in -25C weather regularily. I did tonight for some 3D runs. One particular time there was a blizzard and I killed 2 790FXT-UD5P’s within 24 hours.
-Overclocking and benching with DICE while inebriated
-Plugging and unplugging harddrives and fans while the system is running
-Taken a pellet gun to a lidless 6000+ X2
-Slicing my finger open with an exacto knife while delidding a processor.
-Taking voltage measurements from the wrong spots on my 5870 and nearly killing the card.
-Sometimes for fun, I run 1.9 volts through my chips (555 X2, 955 X4, 1090T X6) on air cooling. I have yet to kill a CPU from voltage.
Hey guys,
Last time i did 5GHz on core #1. Well here is all 6 cores.
Decided to do a little bit of ram clocking for this DDR3 challenge on hwbot.org. Threw my rig on my windowsill, and ran some 32m.
More to come. I hope to compete in the Deneb class as well.
I was really surprised to see what these lovely sticks did today. This is the Mushkin Ridgeback 1600MHz 6-8-6-24 kit. On AMD, it is extremely difficult to run any ram above 2000MHz. Well today I broke a personal record and clocked these sticks all the way up to 2240MHz 8-10-6-15-1T. I used my trusty Gigabyte 890FXA-UD5 & Phenom II X6 1090T Setup.
I did not expect these results at all, actually I did not expect my IMC to allow speeds this high. Turns out I have a great hardware combination. When I was in the BIOS the speeds just kept going up and up. I eventually tightened the timings down to CAS8…which I thought was amazing for a frequency of 2240MHz.
Hey everyone,
My youtube channel is making some ground. After only 9 videos, I have totalled 50,000 views on my youtube videos. The bulk of the views are on my original dry ice overclocking video, The Phenomenal Dry Ice Experiment.
That video started out with a friend and I getting our hands on a Phenom II X4 955 chip and a Phenom II X4 ES. We really intended nothing big with the video, only a simple documentary of our first dry ice run ever. The community loved it, even though it is nothing close to the best overclocking out there (considering most 955′s hit over 5GHz on dry ice). We were noobs, enough said.
Backtracking to my very first video, we go back in time to my first Phenom II chip, the 940 X4. This was the original DDR2 revision of Phenom II, and was the first time we saw the architecture of Phenom IIdo amazing things. My first video involved me, messing around with cold air coming in through my bedroom window, cascading over my TRUE 120 and Phenom II X 940. I displayed the simplicity of overclocking the 940. I did not do any stability testing, however at the time, this was a good suicide overclock for the chip on air cooling. This video netted me nearly 15,000 views to date.
My next video was a tried, but rarely seen cooling method for overclocking. I dubbed this cooling “the slushbox“. This involved me using the H50 Corsair water cooler, and keeping the radiator fully submerged in a cooler filled with ice. The resulting cold got me down to around 10C temps on the CPU (even though the video shows 1C in coretemp, it is inaccurate). I clocked up my Phenom II X6 1090T 4900MHz on 1 core on the chip.
“|Second Frost|” Was one of my proudest moments. The Phenom II X6 1090T under dry ice coolingwas the feature presentation. I also showed clips of my DICE benching methodology (crushing DICE to powder form). I achieved some very good clocks and benchmark speeds. The reason i’m proud of this video, is that it landed on the front page of hwbot.org, and won me Contribution of the Month for November on overclock.net.
I’m looking to keep expanding my subscriber/viewer base. So please link your friends, or whoever will find my stuff interesting. Thanks for checking out my blog and all my videos.
