Neither of those figures matches the 667 MHz figure the tech-support guy said. Not cheap, but cheaper than overhauling the whole motherboard/system to accommodate DDR3 RAM while maintaining 8 cores and up to 32GB RAM.īut CPU-Z tells me my current bus speed is 333 MHz, with a 7.5x multiplier making the FSB 1329.9 MHz. I'm looking at 32 GB of 667MHz FB-DDR2 RAM (needs to be fully-buffered) that I'll probably order tomorrow, for $856. The Dell Tech support guy said the fastest DDR2 RAM my system would support is 667 MHz, which is what most if it on the market is anyway, so that's what I'm looking for.
Broadcom netxtreme 57xx gigabit controller max speed upgrade#
I'm looking to upgrade the RAM to handle these large datasets without crashing my Stats program. USB 2.0 drives, all the other random little stuff you'd expect. Broadcom NetXTreme 57xx Gigabit Ethernet controller SoundMax Integrated Digital HD Audio chipset (which I care little about) Windows 7 Enterprise 64x (often w/ an Ubuntu 10 VMware image running atop) WD2500AAJS SATA2, 250GB (OS & programs) (not top-end, but I don't need a top-end graphics card, and it supports my dual 23" HD monitors just great.)
NVidia Quadro FX 1700, 512 MB memory 460MHz (920 MHz shaders) 333MHz, 5-5-5-15 timings (in addition to size, I'm doubling speed w/ this upgrade.
4x32 KB L1 Data cache, 4x32 KB L1 Instruction cache (8-way) per chip Dual Quad-Core Intel Xeon E5420 2.5 GHz, 1.225V I work in a University Research Lab and am handling some very large datasets (1 file 7.8 GB, needing to crunch stats on it) that are currently maxing out the 8GB RAM on my system. I have a Dell Precision T5400 Workstation.
I'm fairly tech-savvy, but apparently not quite enough to answer this question with 100% certainty.
