Yesterday’s afternoon and today I had a LN2 trip with two AMD setup. I was aiming to break the 7 GHz wall with the trusty Phenom II 955 B.E. and improve my precedent results on socket 939 with the Opteron 148. I failed in reaching 7 GHz with the 955, tho I managed to improve just a little bit my Super-pi 1M score…still not satisfied with it but it is better than nothing.
What is the best way to kill time when you have close to nothing to do ? Easy, run Super-pi 32M using an CPU which takes more than 20 minutes to complete each run…so I did it and killed with easy 8+ hours trying to pull, tho without success, a sub 21 min 32M run with my trusty Opteron 148. Anyway, the result is still kinda worth to be posted here.
Yesterday Crucial released a new firmware for its M4 SSD series, the new version (codename 000F) is supposed to address some issues which used to appear when using the SSD connected to certain SATA/SAS controllers and generally improve stability and reliability. Changes between version 0309 and 000F include the following changes: Improved compatibility with certain SAS expanders and peripheral RAID cards. Improved throughput stability under extremely heavy workloads.
Ten days ago I had an LN2 session together with this Opteron 148; finally today I’ve the time to write a post here and talk about that. .:. SETUP: CPU: Opteron 148 cabrio @1.5*123% volt – CABYE 0536GPMW cooling: Guglio’s CPU pot 2.0 (CPU) and 1.0 (RAM) MB: DFI nForce 4 Ultra-D – bios 623-2 RAM: Corsair PC3500C2 2×256 MB :: Winbond BH-5 – yellow slots VGA: nvidia 6200 LE 256 MB PCI-E
This is the moment we are all waiting for (ok, maybe not really everyone 😀 ). Anyway, after approximately 10 hours of tweaking I came up with a quite interesting result. .:. SETUP: CPU: Opteron 148 cabrio @ 325×10.5 1.5*123 volt – CABYE 0536GPMW cooling: Single Stage phase change MB: DFI nForce 4 Ultra-D – bios 623-2 RAM: Corsair PC3500C2 2×256 MB @ 260 MHz 1.5-2-2-3 1t 3.7 volt:: Winbond BH-5 – yellow slots
Two weeks ago or so I bought a DFI nForce 4 Ultra-D, when it was here I had some fun playing with an old Athlon 64 3000+ core Winchester and some crappy DDR modules. I had also a bunch of Winbond BH-5 kits, too bad they are all dead or semi-dead, so I had to stick with a kit of Micron value PC2700 cas 2.5. Luckily a friend of mine was so glad to send me a kit of Corsair PC3500 cas 2 BH-5, so in the next few days I will have a decent kit of RAM to play with super-pi.
As you can see, it’s quite a long time since my last overclocking related post here. Even the one I’m writing now is not about overclocking, nothing of the latest hardware is interesting at all, so I don’t really bother go out and buy something. When nothing interesting is on the market the things I do is: upgrade the daily use rig. I’m not one of those interested in uber dupah performance, I’m alot more focused on reliability, so I never use the latest stuff for my DU rig…better to have 20 % less of performance but well tested and widely used components.
Think I never mentioned it but I have a small home server, it was built with a c2d E6600, an Intel G965 mobo and some HDDs. Since 2 weeks ago I was using Ubuntu then I decided it was time to try something better and more challenging than Ubuntu, my choice was CentOS. Why use CentOS ? Because it’s one of the best “enterprise class distro” with 7 years support and have a good ammount of interesting features like services GUI manager and iptables GUI.
Today I happen to read somewhere about Intel Rapid Storage and SSD performance. Well, I thought I had already installed it on my notebook but it seems I was wrong, so I did a quick google reserarch and downloaded the software from the Intel site. Someone says this software boosts SSD performance, so I did the usual ATTO benchmark to have a previous / after comparison. before after
Yesterday Crucial released a new firmware for the whole M4 SSD lineup, the update over 0009 version was needed because of the so called “5200 hours bug”. Basicly, every M4 after a power on time of 5200 hours or so will start to hung every hour, this is because something is messed up with the SMART data. This new firmware resolve this bug. Yesterday’s evening I’ve upgraded at this new version of the firmware the M4-128GB I’ve in my Thinkpad.
