Yes, the CPU E7400 exists as in three different flavours:
1. SLGW3 where you have different product codes
2. SLGQ8 where you have one product code
3. SLB9Y where you have two other product codes
(i) BX80571E7400 (Boxed CPU comes with 3 years warranty )
(ii) AT80571PH0723M (Tray CPU comes with 1 year warranty )
Indeed from the link, only the SLGW3 seems to have VT enabled. I don't know why there are different CPUs with different model, may be for marketing and pricing purposes. You may need to be aware that on some board, all SL numbers may not have been validated and tested by the board manufacturers. And one more thing, the board bios needs to have support for some VT as well.
The only way for you to find out which SL number you have, is to remove the CPU from the socket and read it directly from the silvery metal.
All the best,
Same problem here. To buy a retail E7400 you have to use the product code BX80571E7400. You *cannot* specify the "SPEC" code SLGW3. That means you have no guarantee which version you will receive, and it could well be SLB9Y without VT. I have contacted plenty of retailers and asked if they can guarantee that I will receive the SLGW3 but they have all said no. My conclusions are that:
1) Intel are surely now only manufacturing the SLGW3 version of E7400. This started shipping as a retail boxed CPU in August 2009, and was available to OEMs (PC builders) in June 09.
2) There are still many old SLB9Y in the supply chain, especially because OEMs will now only want the SLGW3 version, so Intel are getting rid of old stock in the retail market.
3) The only way to get a VT E7400 is to buy one then check the code printed on top. If it's not the right one, send it back for another. But no retailer will be happy with that.
4) To guarantee you get VT, buy an E8400 for a 50% price increase - but why bother? 3MB extra cache is not worth that much (it makes almost no difference).
5) Intel introducing the SLGW3 E7400 was a complete waste of time and money because you don't know what you are getting. Unless of course you are an OEM and buy thousands or millions direct from Intel, which is exactly who Intel did it for.
6) This leaves individual customers like me ****** off that there is a product I want but can't buy.
Any chance of a reply from Intel and information on how to buy an SLGW3 E7400 here in the UK?
