To put the unit through it’s paces I used the relatively new CPU-torture test program S&M. I’ve found this to be more effective then CPUBurn, or SETI and the program offers extensive monitoring features as well. I verified that the CPU was under LOAD with the Panopsys thermal-throttling and CPU LOAD utility Throttle Watch. In the screenshots below the system is running at default speed (3.4Ghz) first at Idle and then under LOAD (unfortunately S&M needs to be re-set pay no attention to it’s reading of 4216MHz from the previous OC) CPU speed (purple) in real-time is also displayed by Throttle Watch just below the LOAD (green/yellow) display.
In these screenshots the Abit uGuru utility inidicates the 12V rail to be running at a steady 11.84V. This is slightly higher then the Fluke reading, and most likely indicates the inaccuracy of the BIOS and/or software readout. Next I increased the CPU frequency to 250FSB at 1:1 aspect ratio for an overclock of 4262MHz. Vcore was increased from the BIOS default of 1.375V to 1.485V to ensure the system would remain stable. Once again the screenshots indicate voltages under Idle then LOAD.
Although the 12V rail did drop to 11.78V with the CPU overclocked (it’s probably slightly lower) the system ran trouble free under LOAD, without any re-booting. The system was also 3D stable. Given the fact I was running an 18V-DC OASE pump for the Alphacool H20 system, two-120mm Papst fans on the radiator, 2-120mm Tt case fans, a TDK CD/RW, Maxtor SATA and a 3.5 Floppy, the TT-600K04 held it’s own quite well.
TTGI USA has given us yet another fine product at an affordable price. The unit runs virtually silent, except on Turbo mode, although I never had a need for this fan speed. While there were a few short-coming’s such as the absence of rail adjustment (which would have been useful in this case), my only other concern would be the low 12V rail. The P4 550 is perhaps one of the most power hungry CPU’s on the market with a Thermal Design Power rating of 115W, and maximum core amperes at 119A. Overclocked to 4262MHz the P4 550 burns approxmately 162.19W measured via CPU Power Calulator. Given these conditions the TT600K04 did perform it’s job, and should be capable of driving any CPU at default speeds with complete stability. The TTGI-USA TT-600K04 is also available through Dealtime for approximately $110 under the model “Link Depot PNP-600-4F.” I would like to thank Tony at TTGI USA.
